<pre>Occasionally the GPU hangs under normal usage.
I don't know which version to specify since there are so many version among the
xorg packages, possibly xorg-x11-server-Xorg-1.14.4-11.fc20.x86_64
Here is the relevant section of the journal:

Jul 31 21:30:39 worklap kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
Jul 31 21:30:39 worklap kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Jul 31 21:30:39 worklap kernel: [drm] drm/i915 developers can then reassign to
the right component if it's not a kernel issue.
Jul 31 21:30:39 worklap kernel: [drm] The gpu crash dump is required to analyze
gpu hangs, so please always attach it.
Jul 31 21:30:39 worklap kernel: [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Jul 31 21:30:39 worklap kernel: [drm:i915_context_is_banned] *ERROR* gpu
hanging too fast, banning!
Jul 31 21:30:41 worklap kernel: [drm] Enabling RC6 states: RC6 on, RC6p off,
RC6pp off
I will attach the crash dump after I reboot, since X and Gnome are rather
messed up right now.</pre>
