Public bug reported: Hello Ubuntu Linux Kernel Team,
Recently, Ubuntu 24.04 bumped the kernel version to linux 6.8.8 (6.8.0-38.38 pkg version), which introduced an i915 regression affecting GPU accelerated video transcoding on Intel Arc GPU. This bug affects all linux 6.8.5+ kernels and was not fully fixed until linux 6.9.4. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2068087 The issue makes the ffmpeg command fail and throws i915 error in dmesg. `[ 81.026591] Fence expiration time out i915-0000:01:00.0:ffmpeg[521]:2!` https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10895 Could you please backport these two patches to the Ubuntu kernel branch to fix the regression? https://gitlab.com/linux- kernel/stable/-/commit/fdf6c286478698ed901db1bd5a8702667f796c28 https://gitlab.com/linux- kernel/stable/-/commit/e9250578ac6278dfd24a57c326eb805b3bdb0e31 ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Description changed: Hello Ubuntu Linux Kernel Team, Recently, Ubuntu 24.04 bumped the kernel version to linux 6.8.8 (6.8.0-38.38 pkg version), which introduced an i915 regression affecting GPU accelerated video transcoding on Intel Arc GPU.
