I suggest using an older image, preferably with a 4.19.x kernel which are known to be more stable on some machines [1].

Hi everyone,

I'm new to this list so apologies if this is well covered ground. I
recently got a ZX6000 box (2x1.3GHz McKinley, 4GB RAM) and installed the
most recent Debian image (2020-08-19). Installation went fine, but the
system hangs at boot after GRUB loads the kernel (5.7.0-2-mckinley) at seemingly random points. Sometimes the hang is immediate as soon as ramdisk
is loaded, sometime it makes it for ~20 seconds. Most often there is no
error message, but occasionally I see this message:
" watchdog: BUG: soft lockup - CPU#1 stuck for 22s!"

The same system runs HP-UX just fine, so I don't suspect a hardware issue.

Any hints would be much appreciated! Thanks,

John

Hi Adrian,

Thanks for the quick reply. No luck I'm afraid; I tried a couple of images
with kernel 4.9.0 but they hang ~20 sec after boot start (but always at
exactly the same point, unlike kernel 5.7.0 that hang at random points).
But, I'll keep going through them just in case I find one working.

Do you know what kind of storage controller the machine uses? Chances are
you have one of these "hpsa" controllers which require a firmware update
to properly work in SMP mode.

Try booting with "nosmp".

I was able to fix this problem by upgrading the firmware of the controller.

Hi Adrian,

No, these systems use a LSI SCSI controller, and PCI649 (whatever that
might be) for ATA bridge.

I found (the? a?) problem, at least for the image with 4.19.0 kernel. It
tries to load the R100 module for the ATI card in this system, but cannot
find it and hangs. Passing nomodeset to the kernel allows me to boot
(hurray!).

Now I just need to connect this system to the net to start updating / downloading packages.

Thanks for the help!

John
