took a bit to trigger, but finally fired off.

here is a link to the file..: intel_error_decode
http://www.filefactory.com/file/22bypyjhs4mx

the file was to large to send to the list.. let me know if you need more 
info with this.
also if anybody has any ideas to trigger this would be appreciated so 
the bisect can be more precise. right now dont even think its worth it, 
due to not being able to trigger the crash causing the bisect to go 
astray and pointing to a wrong commit(which has happened in the past) 
but then again you never know.

I haven't figured out how to access this thing. Can you please file a
bug report on bugs.freedesktop.org and attach it there?

No worries, it is another ILK hang similar to the ones reported earlier
- it just seems the ring stops advancing. Hopefully it is a missing w/a
from http://cgit.freedesktop.org/~danvet/drm/log/?h=ilk-wa-pile

Oops.. I filed with the kernel. maybe can just add a cc's

well if this means building libdrm etc.. then thats not a problem, more 
time consuming if anything. perhaps an *.rpm that I can test to see?

It's not libdrm, the above is just a kernel git tree with a bunch of
ironlake workarounds.

hmm.. then in that case maybe I should pull and run that kernel to see 
if the crash occurs, before bisecting(if anything).
will do once I get time to download.

$ git checkout origin/ilk-wa-pile

... and you have the right branch checked out. No need for pitchforks
and witch hunts ;-)

[drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung

[Justin P. Mattock]

This is happening both with MAINLINE and NEXT.

basically system is running fine, then under load system becomes really 
sluggish and unresponsive. I was able to get dmesg of the error..:

full log is here: http://fpaste.org/7xH8/

as for good kernels from what I remember 3.6.0-rc1. I can try a bisect 
on this once I get the time. or if anybody has a patch I can test.

Can you please rehand your machine, and then grab the i915_error_state
from debugfs? That contains the gpu hang dump we need to diagnose things.

And the bisect would obviously be awesome.
