From time to time - may be a month or a couple of hours - my computer completely freezes. Everything stops. The screen shows the last image.
Not even the cursor moves. No keyboard key works including the
Alt-PrtScreen keys, like REISUB.
I need to press the power on/off button for 5 secs to restart it.
After restart the journalctl -b -b1 shows nothing at the freeze time.

Do you correlate the failure, with any particular
activity on the machine ?
For example, a more mundane activity on a computer,
is the usage of modern Firefox. While the user is
not viewing a web page, Firefox seems to leak memory
until all available memory in Ring 3 is used up.
But Linux has Out of Memory (OOM) killer, for the
handling of memory exhaustion that way. The system
should not freeze because Firefox happens to be
running.
Whereas, I don't know what happens, if a GPU that
uses shared memory, happens to request more and
more RAM for some GPU activity. An NVidia GPU is
more likely to have its own memory chips, and be
less likely to cause resource exhaustion on its own.
Try running "nvidia-smi" in a terminal window,
selecting the option to have it update the
screen repetitively (like "top" in a sense), and
watch resource consumption listed there. If you're
running the NVidia driver, that program should be
installed for you.
You could run "top" in one terminal window (using
the information near the top of top, for resource info).
And run "nvidia-smi" in a second window, to watch
for dwindling NVidia resources.

If so, I would bet my money on that Plasma5 has leaked memory, in such
case the following bug could be of interest for your: https://bugs.kde.org/show_bug.cgi?id=436061
There ain't much you can do about this, the machine is too occupied with swapping that you won't be able to ssh to the machine. It could be wise
to disable swap and those get the kernel to kill a random process and hopefully it is plasmashell. I have had times when plasmashell has taken
58G of RAM and it's no other option than reboot the computer.

For me it was more to try to be notified before it's get too bad, like logging the output from top* once every five minutes and that way be
able to see memory usage.
* for example use: top -b -n 1 >> /path/to/file/where/you/want/to/log

It's fairly trivial to setup another computer as a remote syslog server

Among enthusiasts, it is popular to stock a spare
power supply. You can fit your spare supply and
retest, and see if that theory holds water.
Right now, the junk room sports a Seasonic S12
as the "designated hitter".
Running Prime95 (statically compiled Linux version
in "Just Testing" mode), while using the existing
supply, is an acceptance test. It tests machine
cooling is adequate (run something lmsensors based,
to see whether temp overshoots, while you're waiting
for the machine to shut off on CPU THERMTRIP). It draws
max CPU power. My machine, wall power climbs to 180W
while running that CPU integrity test.
https://www.mersenne.org/download/
If you have NVidia driver, you can add in a graphics
test if you want, but I don't have anything for that
in mind. I have a CUDA app, but it would be a pig
to set up due to libs and so on. On my machine, running
the graphics test case while Prime95 is running, raises
machine power to 360W (on a 550W PSU). Modern video
cards have a power limiter, and they also have a
status indicator in software, indicating which limiter is limiting
GPU performance. Running NVENC or NVDEC for example,
the card won't use more than 1/3rd of max power.
Normally, my machine power level doesn't go past 200W
without testing assistance like that. 360W to 400W loading,
is via synthetic (unlikely) tests.
*******
Haswell CPUs, at the time, some power supplies would
become unstable at low load, leading to "Haswell certified"
power supplies. But the most likely reason for that
to happen, was the existence of some older supplies
that have (on the label), a row of numbers for
"minimum consumption". No supply created in at least
the last ten years, has that row of numbers on the label.
The absolute worst situation of that type, is there
existed one supply, where the 12V rail needed 25% loading
to remain stable. So if the rail was 40 amps, the label would
read: Naturally, I was careful to never buy a supply
with the two-row MIN/MAX labeling, as it's an admission
of "stupid" in design. You would always be looking over
your shoulder, if you bought the one on the left.
Ancient supply label Modern supply label (zero amps is OK) ... +12V
Min 10A ... +12V Max 40A Max 40A
With lots of computer hardware today, such a guarantee
could not be met in the form of min loading. The idle current
could easily drop below 10A for example. Some modern supplies
have met the "0 amps" requirement, by having a 5W or 10W
load inside the PSU for the purpose of meeting open circuit
stability requirements. It's unlikely an 80+ supply is
doing that.
And here, stability does not mean "oscillation",
stability means remaining in regulation, 12V +/- 5%. If
unloaded, a "MIN/MAX" supply might deviate past 5% by a bit.
12V only gets in trouble, if it drops below 11V, as an example of
how far it can be pushed on overload. Burning might result
(hard drive clamp device activates) at around +15V or so.
There's a bit of headroom on +12V on the high side. Some
other rails don't have that luxury.
A multimeter is recommended, if checking voltages. Do not
trust the ACPI-calibrated voltage readouts for this. The
multimeter might be accurate to around 2% or so. And be careful
with the multimeter probes - one of those modern 1200W supplies,
if you happened to short +12V, it would not be pretty. They
live for the chance to melt wiring. While in theory, individual
wire looms have 20A limiters (PSU shuts off), you don't
want to be testing the cheapness of the company making
the supply, even if you've paid $150 for it. In some ways,
the behavior of the supply, is not adequately captured in
the affixed labeling scheme (specifically, OC protection).
There's been at least one, where it didn't appear
there was adequate loom protection.
In terms of noise patterns, supplies have "ripple". This might
be in the 0.02 to 0.05V range or so. The output capacitors
determine how fast the rail can change instantaneously.
This is a really old schematic now, for PSU education,
but it still illustrates the design principles.
There's 1000uF on the +12V rail for example. Supplies
typically can have 4000-5000 more uF added to the rail
at the load, before it affects oscillation stability.
Precise information of that nature, is hard to get
from a manufacturer, but the designer is aware of
the issue. You can't put 250,000uF across a PC PSU.
http://www.pavouk.org/hw/en_atxps.html
The ATX supply "pushes" but does not "pull". It is
not an op amp or linear amplifier. If the supply
deviates due to transient loading, it likely does
not respond well to energy dumped back into the
supply. Motherboards don't generally do that.
Only one regulator in the whole PC is push/pull. And
that's the regulator for the DIMM terminator resistors,
where the current flow magnitude can be in the +2 amps
to -2 amps range (bus all 0's, bus all 1's). The
regulator must sink the -2 amps, in order to precisely
maintain the terminators at the correct voltage
(otherwise, your PC may suffer the "Photoshop bug").
Most other regulators are the "push only" variety.
A 7805 is a push only regulator. It's not intended
to sink backward current flow.
Summary: I doubt it is the PSU, but... that's why we
test stuff.
Later in the thread I believe OP said it was a laptop. Swapping PSU not
an option. One thing that most likely the cause especially on a laptop
is heat-related hardware issue. Laptops make this a more difficult issue
to deal with, but depending on the laptop I would open 'er up and at
least blow out all the dust. The Dell and Lenovo I have is a simple
process, some other brands, not so much. Looking at the mb caps and
crusty corrosion... My old Latitude D-820 was a lap-roster with nVidia
GPU that was notorious for GPU meltdowns. I cleaned and remount heap
pipes several times and avoided that fate.

Laptops are less debug-able.
The posts I read referred to a "computer".
Setting up a serial port, is the best way
to determine if it is really frozen. I prefer
the SuperIO serial port type, to USB serial.
I use this on the boot line of my newest computer:
console=ttyS0,57600n8
I have a serial cable that runs from the other
machine, over to this machine, where I can monitor it.
The nice thing about ttyS0, is it never moves,
whereas if you use USB serial adapters, you
don't know what the identifier for it is. Maybe
plugging in some other stuff, upsets your debug port.
Not that most people like serial ports, but
I like it. Gets the job done. Works good when
the HID stops working on a setup.

I also played with some configurations, namely giving priority to freqs. because I know that lowering them causes the zone0 temp. to drop quickly. BTW, in the meanwhile I remembered that the freeze problem also
occurred, at least once, with the system in "Slow Mode" this half of

I am using kubuntu 20.04.
Thank you.
First let me explain how I use this computer.
I have a starting (boot) command - cpupower - to set the max. freq. to
2.5 GHz. It's max. value used to be 5.1GHz. Also set the governor to powersave. Let me call this Slow Mode.
This causes my computer to be quiet with very low RPM on both fans. When unplugged from the charger they are most of the time at 0 RPM. Since it
is quite fast, this isn't noticeable.
When I need power, which rarely happens - training AIs or processing
large amount of data, I set it to the max. freq. and governor to
performance. I also do this for my FS :-) Let me call this Fast Mode.
Now, about this problem ...
1. I configured nvidia to ondemand. The freeze problem never occurred anymore. But since it could not occur for a month or more, its
inconclusive yet. Anyway, from lots of things I have being reading it is
very likely that BIOS, for some reason, can't cool something going wrong
and just freezes the computer. So, no logs. Once again, inconclusive.
2. A new problem
When in Fast Mode, using a job with fullcpu causes a shutdown.
This time there is a log entry:
"thermal thermal_zone0: critical temperature reached (110 C), shutting down" So, I tried to analyze the problem.
I monitored zone0 temperature and could see it goes up until 102C. Then
the computer initiates the emergency shutdown. So, the monitor gets
probably killed. Notice that the critical temp. for this zone is 100C.
I tried again but when the temp. of zone0 reached 99C I put the fans in
boost mode (max. speed) and the temperature dropped and got stable at 97C.
I tried this again, but now I just put the computer in Slow Mode. The
temp. drops to 40-50C!
So, why neither thermald or even the BIOS use these resources to drop
the temperature? In fact the fans rotate at higher speed but do not
reach the 6k RPM of boost mode. I tried several configurations for
thermald, including give priority to acting on freqs. No success. It
seems that thermald doesn't seem to care at all with its configs.
Finally
=======
If I reboot the computer:
Then it seems OK.
I put it in Fast Mode, execute a fullcpu job and zone0 temp. keeps
stable at 97C!
If I suspend the computer, when restarting the problem starts again!!! I tried this few times last couple of days.
Notice that all these problems are relatively recent.
By the way ... in windows this problem does not occur.
So:
SW problem, after an upgrade perahps? HW problem? Both?
I feel myself lost ...
As soon as I get some time, I'm thinking to install a new distro in a different partition and see what happens there.
Until there, before I start a CPU intensive job I need to reboot before.
Not bad ... :-)
Thank you to all who responded and for any further comments or suggestions. Paulo
I am getting an occasional freeze as well. Yesterday, in the midst of a Google Meet seminar I was delivering!. iAlmost Complete freeze on my end. No keys worked, screen frozen. Except that the people watching could still
hear me and see me and I could hear them. Alt-ctrl-F2 worked, so Linux was still running in
the background. I could not figure out how to unfreeze the google-meet
full screen and had to do the power button thingy. Of course then
another bug showed up. -- I sometimes run my laptop with a desktop
monitor attached. Often the second or third time I reboot, the system
seems to get completely confused and look for that second monitor as the default after it is run the "new hardware" search. It then times out (90
sec) on starting up akonidia(?) and then another 30 sec pause.starting
up something else, and spew out many pages of error/waring stuff befor
the boot process finished. So it took almost 5 min to reboot in the
midst of my seminar. Sheesh.

If you mean the thermal issue, maybe you need to restart thermald after

work well with suspension.
I also played with some configurations, namely giving priority to freqs.

From a hardware perspective, some subsystems share power envelope
because they're in the same package (Intel CPU and Intel HD 630).
Or, they can share a common heatpipe, which means if one gets
hot, both get hot (Intel CPU and NVidia GPU chip share heatpipe).
The NVidia chip, should have an NVidia driver which controlsIt's supposed that thermald takes actions to low the temperature. Per
frequency and voltage as a function of "what limit you're hitting".
On something like Furmark, you would be power limited. Maybe
the GPU driver throttles (turns down clock) when the chip gets
too warm. And this means, you could even be in a situation where
a railed or turboed CPU causes the GPU to slow down.
It's beyond my pay scale, to balance all these things, but fromAs I said before, thermald should have taken actions at 90C. This is the
the looks of it, some feedback loop in your laptop is not working
as expected. When the CPU goes above 100C, it should start throttling.
The NVidia chip should have a throttle temperature too. And the
NVidia throttle point should take the GPU temperature measurement
error into account.

Hi all!
From time to time - may be a month or a couple of hours - my computer
completely freezes. Everything stops. The screen shows the last image.
Not even the cursor moves. No keyboard key works including the
Alt-PrtScreen keys, like REISUB.
I need to press the power on/off button for 5 secs to restart it.

ondemand status. No success. Sooner or later it freezes.
Is there a way to get some information on what this is happening?
I am using kubuntu 20.04.
Thank you.
First let me explain how I use this computer.
I have a starting (boot) command - cpupower - to set the max. freq. to
2.5 GHz. It's max. value used to be 5.1GHz. Also set the governor to powersave. Let me call this Slow Mode.
This causes my computer to be quiet with very low RPM on both fans. When unplugged from the charger they are most of the time at 0 RPM. Since it
is quite fast, this isn't noticeable.
When I need power, which rarely happens - training AIs or processing
large amount of data, I set it to the max. freq. and governor to
performance. I also do this for my FS :-) Let me call this Fast Mode.
Now, about this problem ...
1. I configured nvidia to ondemand. The freeze problem never occurred anymore. But since it could not occur for a month or more, its
inconclusive yet. Anyway, from lots of things I have being reading it is
very likely that BIOS, for some reason, can't cool something going wrong
and just freezes the computer. So, no logs. Once again, inconclusive.
2. A new problem
When in Fast Mode, using a job with fullcpu causes a shutdown.
This time there is a log entry:
"thermal thermal_zone0: critical temperature reached (110 C), shutting down" So, I tried to analyze the problem.
I monitored zone0 temperature and could see it goes up until 102C. Then
the computer initiates the emergency shutdown. So, the monitor gets
probably killed. Notice that the critical temp. for this zone is 100C.
I tried again but when the temp. of zone0 reached 99C I put the fans in
boost mode (max. speed) and the temperature dropped and got stable at 97C.
I tried this again, but now I just put the computer in Slow Mode. The
temp. drops to 40-50C!
So, why neither thermald or even the BIOS use these resources to drop
the temperature? In fact the fans rotate at higher speed but do not
reach the 6k RPM of boost mode. I tried several configurations for
thermald, including give priority to acting on freqs. No success. It
seems that thermald doesn't seem to care at all with its configs.
Finally

I don't know much about Ubuntu flavors (using MX-Linux myself) but the
fan speed can also be controlled by the OS, depending on how your
Kubuntu is configured:
https://askubuntu.com/questions/22108/how-to-control-fan-speed
Sometimes hardware (or a BIOS) does this on purpose. For example, my
DOCSIS modem for internet access has a fan that never needs to come on because we never stream movies and stuff like that. Very little work for
the processor. Sometimes the fan still goes to full blast for a few
seconds, then off. I guess they programmed it that way to avoid the fan becoming "caked up" and stuck. Just like with a power generator, you
have to run it once a month or it might not start in a crisis situation.

I have used two machines with limited cooling; one is a mini computer
box, fanless (idea is to be put on sitting room by the TV). When it is
doing something intense, it overheats and it throttles the CPU down.
Another is a laptop I prepared for another person, with a relatively
fast processor that can overheat if you demand some job for minutes, and
then it throttles down.
Both seem to be designed for this; be running normally with a small
load, but sprint on demand if the user needs to run something. But they
can not keep up the load for a long time because they have no fan, or a
too small fan.
Now, I did not install any daemon or configure anything, it was the
kernel itself doing it all, our of the box.
Both have only Intel graphics.
The minipc is a "msi CubiN Mini-PC" (I can't find exact model), cpu is "Intel(R) Pentium(R) CPU N3710 @ 1.60GHz" (4 cores)
The laptop is "Lenovo ThinkPad E15 Intel Core i5-10210U/8GB/512GB SSD/15.6"

At least the sensors are working - I can monitor them and, at least,
lowering the CPU's freqs result in temps lowering. Also the fans are
able to go to higher RPM. If I manually put them in boost mode, they are
able to stop the temp rising!
Immediately after (re)boot the system never goes above 97ºC!
About Opensuse ... that was the best and more stable distro I have ever

lack of information or packages, and the unavailability of some library sources for development. In debian likes I just need to install <lib name>-dev. One example was libgcrypt20.

Hi all!
From time to time - may be a month or a couple of hours - my computer
completely freezes. Everything stops. The screen shows the last image.
Not even the cursor moves. No keyboard key works including the
Alt-PrtScreen keys, like REISUB.
I need to press the power on/off button for 5 secs to restart it.
After restart the journalctl -b -b1 shows nothing at the freeze time.
I changed my NVIDIA driver to 470. I also tried to put the driver in
ondemand status. No success. Sooner or later it freezes.
Is there a way to get some information on what this is happening?
I am using kubuntu 20.04.
Thank you.
sounds like something to do with the ram. Disable XMP.

I did run OpenSuSe at my two previous jobs, sure there was shortcoming
with getting packages, but as Carlos already pointed out the dev
packages are in a different repository. And of course you can get hold
of all the SRPMs too in case you want to make some changes to a package.
It's not the distro I would use at home, for me metadistributions has
been more in my taste except the time it takes to build all the packages.

In the comment https://github.com/intel/thermal_daemon/issues/268#issuecomment-788709112 it's mentioned that the thermald works after suspension after a patched version was used.
As I understand you can increase the debug information to get more info

The patch is included in the last version.
With the version of kubuntu 20.04:
- I have tried --adaptative and --ignore-cpuid--check. It didn't
complain but I could not determine if they are both active.
It should be expectable that the patch was back ported to kubuntu 20.04. Anyway ... I'll try the last version again, but this time with both
switches active, to see what happens.

I saw yesterday this command to zypper:
source-install (si) name...
Install specified source packages and their build dependencies. If the name of a binary package is given, the
corresponding source package is looked up and installed instead.
This command will try to find the newest available versions
of the source packages and uses rpm -i to install them, optionally
together with all the packages that are required to build the source
package. The default location where rpm installs source packages to is /usr/src/packages/{SPECS,SOURCES}, but the values can be changed in your local rpm configuration. In case of doubt try executing rpm --eval "%{_specdir} and %{_sourcedir}".
Note that the source packages must be available in repositories you are using. You can check whether a repository contains
any source packages using the following command:
$ zypper search -t srcpackage -r alias|name|#|URI
$ zypper search -t srcpackage -r alias|name|#|URI

For Mageia, the isodumper program/package from the Mageia repos. When
writing an
image to a usb stick, with the option to add a persistent partition
selected, it
uses dd to write the image, then adds an ext4 partition to the remaining space with
the label mgalive-persist. The Mageia live iso images look for the
partition, and if
found mounts it as an overlayfs so all changes made, including
installing additional
packages, are stored for later use.
At least my network wifi configuration goes to the new installed system.Just one more question I forgot ...
Is it the same to install from the live image or is it better to
download the installer image? I'm asking because I never found a distro

When installing from a live iso, the contents of the iso (all files seen
when
it's booted, not the iso file itself) are copied to the selected/mounted
file
systems. If installing while running in live mode, and selecting the
install
from the running live system, the changes made in live mode, including
those
stored in the mgalive-persist file system, are included.
I expect other distros that support persistence use similar packages and methods.

Downloaded the 900MB "LiveDVD" one.
https://sjc.edge.kernel.org/opensuse/tumbleweed/iso/openSUSE-Tumbleweed-KDE-Live-x86_64-Snapshot20211016-Media.iso
Shows an install icon, but it will probably
be doing some sort of network install, with
some delays while it gets stuff from the network.
Whereas the 4GB version will at least have a few
files onboard.
For a one-off install, the 900MB might be the answer.
If you think you'll be installing more than once,
then it might be more important to get a larger
piece of media.
This is what I see in a VM, when clicking the Install
icon in the 900MB one.

If that's the "Tumbleweed-KDE-Live" you can just cancel the install and use the system as is, no installation.

OK, let's say I want to give opensuse a try.
People just use a live Flash drive to try things. They don't install
anything.
Downloaded the 900MB "LiveDVD" one.

That one is intended to be run as is, on the USB stick, without
installation, although installation is possible. There should be a KDE version, another GNome, another XFCE, and another dedicated to rescue
work (the later two might be the same one).
All of them are intended to copy with dd from the image to the USB
device (say, /dev/sdb), destroying all the partitions (creates new
ones). On the first run they create a read/write partition where you can
save files. It is possible to add some packages with zypper (not the
kernel, though).
Don't try to "make them bootable", that would destroy them. Just copy to
the stick, unmodified, with dd or dedicated programs (as described in
the openSUSE wiki).
Then there are two other images, one of about 4GB (the DVD) and another
mall one for network install. Those are the pure installation images,
can not be "run". That is, of course they boot and run but what you get
has only the purpose of installation.
Shows an install icon, but it will probably
be doing some sort of network install, with
some delays while it gets stuff from the network.
Whereas the 4GB version will at least have a few
files onboard.
For a one-off install, the 900MB might be the answer.
If you think you'll be installing more than once,
then it might be more important to get a larger
piece of media.
This is what I see in a VM, when clicking the Install
icon in the 900MB one.

When a person wants to run a specific graphics driver,
an install comes in handy for that case. Even a USB stick
with persistence would do, but persistence easily exhausts
the 4GB formulation, and it helps to have a larger
casper-rw than that. I think Rufus can do that (rufus.ie).
You might need a specific graphics driver, to get a machine
hot enough to tip over.

Hi all!
From time to time - may be a month or a couple of hours - my computer completely freezes. Everything stops. The screen shows the last image.
Not even the cursor moves. No keyboard key works including the
Alt-PrtScreen keys, like REISUB.
I need to press the power on/off button for 5 secs to restart it.
After restart the journalctl -b -b1 shows nothing at the freeze time.
I changed my NVIDIA driver to 470. I also tried to put the driver in
ondemand status. No success. Sooner or later it freezes.
Is there a way to get some information on what this is happening?
I am using kubuntu 20.04.
Thank you.

The current situation:
1. The sporadic "fan jets" are from the normal fan. Not the GPU one.
2. The "freezes" origin still unknown. Now I am almost sure that it does
not come from the BIOS. In fact, during a freeze, there was one
occurrence of several continuous "fan jets".
3. A couple of "fan jets" also occurred once while in the grub menu!
4. The uncontrollable rising of temperature of /sys/devices/virtual/thermal/thermal_zone0/temp at full cpu after suspend/wake also occurs with opensuse leap 15.3 live. Before
suspending, that temperature is kept stable at 97ºC.
I tried to use several kernels available in kubuntu, including an intel version 5.13, but I was unable to get them boot in graphic mode - nvidia
470. Some more ... time and I'll try it without Nvidia drivers.
Thanks for your attention.

How long has the CPU been in place under the heat sink. The grease or thermal paste used can dry out and lose heat conductivity.

sensors/cooling system. But what I do not understand is why the
temperature gets controlled, by the kernel perhaps, before first
suspension and not after waking from suspension!
I have tried Opensuse and Clear linux. All have the same problem.
I have written a small script that successfully controls the temperature
just changing the CPU's freqs. I don't know how to act on the other
cooling systems. thermald, which was supposed to do this, fails miserabilly.
