The contents of /sys/class/drm/card0/error
3.14.5 kernel

Running a custom OpenGL application and this issue occurred resulting in the
OpenGL application no longer rendering
Kernel messages as follows:
[51630.220152] [drm] stuck on render ring
[51630.220163] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[51630.220167] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[51630.220170] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[51630.220173] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[51630.220176] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[51636.201578] [drm] stuck on render ring
[51642.202965] [drm] stuck on render ring
..... keeps going indefinitely ....
After I copied /sys/class/drm/card0/error to /tmp, the system automatically
recovered and continued rendering as if there was no problem.</pre>
