I saw that the 5.14 kernel now includes an Intel-developed driver for
Intel M.2 WWAN modules, specifically the XMM 7560, which I have in my laptop. It is supposed to integrate with the WWAN subsystem, which in
turn integrates with ModemManager. However, when I installed the 5.14 kernel, I can see a wwan0 interface, but I can't bring it up. I got
output basically identical to those here: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/ 385#note_1087439

You did not specify the distro you are using BUT the kernel you wish to use must be the one available from the distro repos you are using otherwise you will be missing dependencies and the kernel (+modules etc) will be incomplete. Note that you can get error messages for this in the log
file/s but you will need to look very closely.

I am using Ubuntu 21.04, and I got the kernel from the Ubuntu Mainline PPA, but it doesn't include any Ubuntu patches, etc, so I guess that could be causing problems.
Output from lspci shows the device as using the iosm driver, and I get a wwan0 interface, but I guess something else is broken, and I will have to wait until the 22.04 release (next Ubuntu release will still be using the 1.13 kernel) or use a different
By the way, how would I see if a module isn't getting loaded?
By the way, how would I see if a module isn't getting loaded?
You can see which modules has been loaded with "lsmod" or
"cat /proc/modules". You might also get a hint about why a module does
not work as expected by studying the output from "dmesg".
Any ideas on why this would be happening? The correct driver is loaded
and ip link lists the interface as using the iosm driver.
already. It depends on what you need to do if you need specific Ubuntu programs or are simply used to using that Ubuntu mess which KDE Plasma 5
can be configured to imitate.
