[73646.381899] [drm] GPU HANG: ecode 0:0xf4e9fffe, in Xorg , 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.

i'm guessing this should have been a duplicate of the other Intel driver bug that was erroneously resolved as duplicate of that LibreOffice UI design bug :)
