[Bug 2084883] Re: Video playback on AMD 780m crashes system

Hi Jakub,

I think... I think this is actually fixed in Oracular already. But not
in the firefox snap.

If you read this Arch Linux thread:

https://bbs.archlinux.org/viewtopic.php?id=298273

Do you happen to get the green blocks?

https://gitlab.freedesktop.org/drm/amd/-/issues/3437

I think this might fix it:

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30510

Its in mesa, and not the kernel. This landed in mesa 24.2.0, and
oracular has 24.2.3, so the patch should be there.

Are you using the snap version of firefox? If you do, it has an outdated
version of mesa from what orcaular is using, and snaps use their own
libraries and not system libraries.

If you install firefox manually:

https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-
firefox-deb-package-for-debian-based-distributions

This will use the system mesa instead. Does it still crash?

Thanks,
Matthew

Title:
Video playback on AMD 780m crashes system

Status in linux package in Ubuntu:
New

Bug description:
During video playback on Youtube/Firefox, screen turns off for several seconds then comes back up. It usually happens 2-3 times and then it stays black. Video seems to be running in background (i still hear audio) during screen resets, however I mouse and keyboard are unresponsible. Alt-sysrq-o successfully shuts down the machine.
I am using KWin (current git version).
The bug does not happen every time, but about once a day. It never happened on 24.04 with 6.8 kernel.

Attached is journalctl --system output showing kernel errors related
amdgpu/VCN problems.
