I'm regularly having troubles with GPU hangs (at least it says so in the logs - I attached one of them). This one happened after returning from suspend. I'm not quite sure which versions are important, I'm running mesa 12.0.1-2, libdrm 2.4.70-1 and xf86-video-intel 1:2.99.917+676+g26f8ab5-1 on a current&updated archlinux. Do you need any more information?

Error log after suspend
The machine is a Thinkpad x240 with a Intel Core i5-4300U
Hopefully /sys/class/drm/card0/error has more clues. Please attach following the hang upon resume (use cat, and grab it before rebooting).

Second example from journalctl
It just happened again, here's another exert from journalctl. Unfortunately I couldn't get /sys/class/drm/card0/error again because the whole system died on me. Hope this helps

Second example from /sys/class/drm/card0/error
... I'm attaching it anyways - maybe it helps even after a reboot?
Can I in any way help by providing more information and speed up the progress of a fix? It's really bugging me, I can't use my laptop like this and it neither works properly with the LTS nor with the current linux kernel.
