Hello,

I have embedded system on Intel Atom Z8350 that run Ubuntu 16.04 with X11
server + ffmpeg H264 transcoder + mpv h264 video stream player + ffvademo to
show web camera H264 stream. Every hour it have an error:
[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe C
(start=3143204 end=3143205) time 916 us, min 1073, max 1079, scanline start
1054, end 1116
But then after about 24-48h it hangs on GPU:
[58796.141184] [drm] GPU HANG: ecode 8:2:0xbffffffe, in ffmpeg [1311], reason:
Hang on vcs, action: reset
[58796.141188] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[58796.141190] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[58796.141191] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[58796.141192] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
