Kernel panic on suspend/shutdown

[Alexander Krosch]

On (so far) spontaneous suspends (to RAM) or shutdowns, a kernel panic (blinking caps lock) will happen in roughly a third of the cases (felt, not measured). So far this has not happened when suspending manually through plasma.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

the LTS it came with, so I installed kubuntu 15.04 and the problem appeared
right from the beginning.
It didn't happen with 14.04LTS though, but that is unusable for other
reasons.

Of course.

I seem to have the same problem also on a Dell XPS 13 (2015) but with A03 BIOS. Currently running Kubuntu 15.04, Kernel 3.19.0-24-generic. Only I have the kernel panic 100% of the time when suspending from KDE either by closing the lid or from the KDE menu.

But I've found a tempory workaround. I've made a program starter with the following command line:

qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock ; sudo pm-suspend

and put the following file into /etc/sudoers.d:
mb@rhea:~$ cat /etc/sudoers.d/pm-suspend
Cmnd_Alias SUSPEND = /usr/sbin/pm-suspend

%sudo ALL = NOPASSWD: SUSPEND

This locks the screen and goes into suspend flawlessly. So it must be something about the way KDE does suspend.
