Here's another one I had lying around in pstore. Note that this one has
slighty older kernel and BIOS version, possibly eliminating a couple of
variables.
<6>[18285.732012] [drm] GPU HANG: ecode 9:0:0xfffffffe, in Xorg [842], reason: Hang on render ring, action: reset
<6>[18285.732024] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
<6>[18285.732028] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
<6>[18285.732032] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
<6>[18285.732036] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
