/sys/class/drm/card0/error when running firefox http://www.google.com/chrome/

Relevant dmesg print:
[  151.816215] [drm] stuck on render ring
[  151.817277] [drm] GPU HANG: ecode 4:0:0xf41b8c79, in firefox [2491], reason:
Ring hung, action: reset
[  151.817279] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  151.817281] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  151.817282] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  151.817284] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
