Comment 36 for bug 1980831

OP from Gitlab here, just updated to Ubuntu 23.04 and am currently running kernel 6.2.0-20-generic.

I still had the issue until 5.19.0-41-generic.

So far the system has only crashed once, but it was after reboot, all the screens stopped working, but then the screen connected to the nvidia gpu came back, everything else connected to amd gpu stayed frozen, and then nvidia screen stopped working as well.

x system boot 6.2.0-20-generic Sat Apr 29 12:06 still running
x :0 :0 Sat Apr 29 11:55 - crash (00:11)
x seat0 login screen Sat Apr 29 11:55 - crash (00:11)
reboot system boot 6.2.0-20-generic Sat Apr 29 11:55 still running
reboot system boot 5.19.0-41-generi Sat Apr 29 10:11 - 11:53 (01:42)
reboot system boot 5.19.0-41-generi Sat Apr 29 10:05 - 10:06 (00:00)
reboot system boot 5.19.0-38-generi Sat Apr 8 22:11 - 10:03 (20+11:52)

reboot system boot 5.19.0-38-generi Sat Apr 8 21:59 - 22:01 (00:01)

I wasn't able to get any logs that might explain the crash, but I will keep you posted if this solved the initial issue I'm having.

If issues start happening again, I'll go back to testing bleeding edge amd drivers on kisak repo.

EDIT: now that I read tnxhawks comments, I might be experiencing similar crashes, will update on that regard as well, but my initial issue was just related to the AMD driver freezing GUI with the following message: kernel: [drm:amdgpu_dm_commit_planes [amdgpu]] *ERROR* Waiting for fences timed out!
