Created attachment 115502 [details]
/sys/class/drm/card0/error (GPU crash dump)

Appeared after turning on a va-api hardware acceleration.

Dmesg:
[  904.206843] [drm] stuck on render ring
[  904.206866] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[  904.206872] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[  904.206876] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[  904.206896] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[  904.206902] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Your seqno writes to the HWS vanished.

Timeout, this is very old bug with no activity so closing it.

Aleksei if this issue still occurs, please ensure that you are using latest component version (kernel, libva ...) and then open a new bug with kernel log and gpu error dump
