dmesg
getting unrecoverable GPU hang with error:
Apr 28 23:37:00 dhcppc14 kernel: [drm] GPU HANG: ecode 8:2:0xfffffffe, in
DVDPlayerVideo [1027], reason: Ring hung, action: reset
Apr 28 23:37:00 dhcppc14 kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
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.</pre>
