Nothing untoward or outlandish in the batch or ringbuffers. Can I ask whether this bug only occurs with recent kernels or disappears with the latest? I am unable to reproduce a similar crash on linux kernels < 3.13.6. I could test on the mainline kernel if that would be helpful. Created attachment 96257 [details]
/sys/class/drm/card0/error.gz
I've had to gzip the error because of upload size limitations.
Well this is a hsw and it sounds like 3.13 works flawlessly. Can you please try to bisect where this regression has been introduced? Created attachment 96633 [details]

At random times, my screen freezes and I have to restart X. Nothing appears in X.org log, but there is this in dmesg:
[ 6513.878111] [drm] stuck on render ring
[ 6513.878120] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 6513.878123] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 6513.878124] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 6513.878126] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 6513.878128] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
Then the log get spammed with the first of those lines. I think this started to happen like a month ago (either from mesa, intel or kernel update), together with random font rendering corruption (where random set of letters are replaced with black boxes).
I’m running an up-to-date arch linux install, on a Core i7-4702HQ.
So I think I may be affected too. However, I don’t know how I could help you in any way, I’m new to bugreporting.
