<pre>I'm using the kernel described in <a class="bz_bug_link

title="NEW - [HSW] GPU HANG: ecode 0:0x87d3bffa on ctx load"
href="show_bug.cgi?id=83677">bug 83677</a> - basically #requests backported to
3.17.0. This may turn out to be a duplicate of that bug.
While it's now harder to get a GPU hang, I've had one with lots of VA-API video
decodes. dmesg gives:
[ 2327.073906] [drm] stuck on render ring
[ 2327.082270] [drm] GPU HANG: ecode 0:0x8fdffff8, in screen_manager [903],
reason: Ring hung, action: reset
[ 2327.082273] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2327.082274] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2327.082275] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2327.082276] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 2327.082277] [drm] GPU crash dump saved to /sys/class/drm/card0/error
I'll attach the gzip'd error state.</pre>
