I've faced with the similar issue, and it become more and more annoying, here
is the message from dmesg:
=====
[drm] stuck on render ring
[drm] GPU crash dump saved to /sys/class/drm/card0/error
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
[drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0x7728000 ctx
5) at 0x7728220
=====
I'll attach suggested error dump in a couple of minutes. Since one month I'm
facing the problem when the everything is completely stuck on my screen. At
first I tought that's something related to my windows manager, but during
dubuging session, I've found the messages pasted above. 
I have updated to 3.13.0-rc4 kernel, limited amount of GPU in system to 1 in
kernel. 
This occur at least once per day. 
Please let me know what kind of info is needed and I'll get it for you.
