I'm filling this bug in order to inform the last 5.19.x kernel doesn't permit to use GPU HW acceleration. The previous 5.18.x works perfectly. This is the dmesg: ago 18 14:16:54 abc kernel: i915 0000:00:02.0: [drm] Resetting vcs0 for preemption time out ago 18 14:16:54 abc kernel: i915 0000:00:02.0: [drm] Plex Transcoder[77988] context reset due to GPU hang ago 18 14:16:54 abc kernel: i915 0000:00:02.0: [drm] GPU HANG: ecode 8:4:a8ffdf3d, in Plex Transcoder [77988] ago 18 14:17:09 abc kernel: i915 0000:00:02.0: [drm] GPU HANG: ecode 8:1:85d4fffb ago 18 14:17:09 abc kernel: i915 0000:00:02.0: [drm] Resetting rcs0 for stopped heartbeat on rcs0 (tested on 5.19.0, 5.19.1 and 5.19.2) ciao luigi Reproducible: Always Steps to Reproduce: 1. Boot kernel 5.19.x 2. Start a GPU HW transcoding (via vaapi/Plex) 3. system hangs Actual Results: System Hangs Expected Results: GPU HW transcoding should works Kernel 5.18.x works
Can you try by passing the argument enable_guc=2 to the i915 module ?
I see similar bugs around this upstream. Can you please report this upstream? There are two open relevant bugs I see: https://gitlab.freedesktop.org/drm/intel/-/issues/3740 https://gitlab.freedesktop.org/drm/intel/-/issues/3398 There's also instructions on how to report i915 bugs: https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs
