Compressed error state

This is the error state; dmesg to go with it says:

[ 2964.222067] [drm] stuck on render ring
[ 2964.222090] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 2964.222102] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2964.222114] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2964.222119] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2964.222125] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
