/sys/class/drm/card0/error output

I was editing a document in LibreOffice when everything on the screen, except
the cursor, froze. Nothing could be done for about 15 seconds, and then the X
server restarted and I was presented with the login screen. 

dmesg reported the folowing:
[ 4210.818086] [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [2611], reason:
Hang on rcs0, action: reset
[ 4210.818090] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 4210.818090] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 4210.818091] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 4210.818092] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
