[73646.381209] [drm] stuck on render ring

[73646.381899] [drm] GPU HANG: ecode 0:0xf4e9fffe, in Xorg [1224], reason: Ring
hung, action: reset
[73646.381904] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[73646.381916] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[73646.381917] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[73646.381919] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[73646.381921] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[73646.382457] [drm:i915_context_is_banned] *ERROR* gpu hanging too fast,
banning!
[73648.380691] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

Running into this on 3.15.8-200.fc20.x86_64. GFX still moderately functional,
though overlays and context menus in Gnome 3.12 are simply black. Will attach
error state soon.
