error log
We seem to have neglected the bug a bit, apologies. The issue is occurring in bsd ring. Reassigning to libva component. There were improvements pushed in kernel and libva that will benefit to your system, so please re-test with latest kernel & libva and mark as REOPENED if you can reproduce (and attach fresh gpu error dump & kernel log) and RESOLVED/* if you cannot reproduce. Besides kodi, can you reproduce this issue with other vaapi based player? Did you reproduce this issue with a specific video file? If yes, is it possible to share the video file? It seems to be working fine (without visible effects) since 4.8 kernel. Currently I run Fedora 24 with following components: kernel: 4.8.11-200.fc24.x86_64 libva-1.7.3-1.fc24.x86_64 libva-intel-driver-1.7.3-1.fc24.x86_64 kodi-16.1-3.fc24.x86_64 ffmpeg-libs-3.1.5-1.fc24.x86_64 Uptime since last update/reboot is 5 days and there is only one error in dmesg which doesn't seem to affect anything: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=81437 end=81438) time 290 us, min 1074, max 1079, scanline start 1067, end 1067 So I'm closing this BZ as fixed. |

Apr 28 23:37:00 dhcppc14 kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel Apr 28 23:37:00 dhcppc14 kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. Apr 28 23:37:00 dhcppc14 kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. Apr 28 23:37:00 dhcppc14 kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error Apr 28 23:37:00 dhcppc14 kernel: [drm:i915_reset_and_wakeup] resetting chip Apr 28 23:37:00 dhcppc14 kernel: drm/i915: Resetting chip after gpu hang Reproducible 100% after starting video playback via vaapi backend. Kernel: 4.6.0-0.rc5.git1.1.fc25.x86_64 kodi: 16.0 libva/libva-intel 1.6.2-1 It 'works' with kernel-core-4.6.0-0.rc0.git1.1.fc25, where occasionally video hangs with: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun but it's recoverable by stopping playback or skipping to playing the next video file.
