/sys/class/drm/card0/error
Running Ubuntu's 4.11.0-6-generic kernel, whenever Facebook loads a webGL
widget in Google Chrome my screen locks up for a few seconds. When it comes
back, Chrome reports that webGL has crashed and I see this in the kernel log:
[121807.432832] drm/i915: Resetting chip after gpu hang
[121807.433343] [drm] RC6 on
[121807.448255] [drm] GuC firmware load skipped

I've attached the contents of /sys/class/drm/card0/error.
