i915_error_state

I currently experience frequent CPU hangs.  These started some time ago; I'm unsure whether they came about by a driver, Xorg, or kernel update.  They happen without doing anything specific.

Software versions:
  - Xorg 1.13.1
  - xf86-video-intel: 2.20.19
  - Linux kernel: 3.6.11

Hardware:
  - Core i5-2400 (model 42, stepping 7)
  - CPU-integrated Intel graphics

Attaching a sample error state.
Comment 1 Marco Götze 2013-01-24 08:31:52 UTC 
Note: I've intermittently set the following kernel parameters, without any apparent impact on the issue's occurrence:

  i915.i915_enable_rc6=0
  i915.semaphores=1
Comment 2 Daniel Vetter 2013-01-24 10:09:18 UTC 
Can you please reteste with latest 3.8-rc4 kernel? We've fixed a few gpu hang bugs on snb just recently, so would be good to rule those out.

Comment 4 Marco Götze 2013-01-25 14:06:06 UTC 
I've meanwhile upgraded the kernel to 3.8.0-rc4 (as has been asked), and xf86-video-intel to a git revision of some time yesterday (commit 778dba90).  I still get hangs, but these can be recovered by switching to the console and back to X.

Attaching a new error state.
