Full kernel log - line 5251

SUMMARY

Wayland session crashes and goes to a black screen requiring a reboot

The kernel logs mention org_kde_powerde and org_kde_powerdevil

STEPS TO REPRODUCE
1. Use the wayland sessions normally. Issue seems to happen randomly.

OBSERVED RESULT

The whole wayland session crashes and you are brought to a black screen, which shows no response to keyboard input. Kernel logs show that the kernel is still at least recognizing REISUB (i had it disabled at the time though so i couldn't use it), so i don't think it's the problem.


EXPECTED RESULT

Wayland session does *not* crash

Kwin crashed. Kwin crashing just makes everything quit.

From a powerdevil POV, it's not a bug, so I'll close this.

We still have a kwin crash. Do you remember what you were doing at the time?
Ideally we also need to get a backtrace.

I have not been able to reproduce it yet unfortunately. It's very random. I was in spotify at the time switching a song, and then i went and minimized the window and opened dolphin. Further, i'm not really sure how i could grab the backtrace?
