GPU crash dump

I was just watching a video on youtube and clicked to fullscreen.
After that the screen goes blank and I needed to restart the window manager/XOrg with Ctrl+Alt+Backspace.

Searching the /var/log/messages I found the messages below:

Interesting. I had not noticed any crashes like this before, but it is consistently happening when I direct chromium at https://ello.co/beta-public-profiles and attempt to hit 'login'.

Additional output this time:
[  435.806361] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0xfe3b000 ctx 0) at 0xfe3c9e0
[  435.864015] [drm] GMBUS [i915 gmbus vga] timed out, falling back to bit banging on pin 2
[  436.312016] [drm:i915_reset] *ERROR* Failed to reset chip.

^ Gah. Please ignore my previous comment; I am new. That was intended for bug #84160, with a duplicate title... :/
