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] /sys/class/drm/card0/error 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.

[ 6513.878128] [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.
