Subject: i915 drm crashes with link to relevant i915_error_state

I've put up the i915_error_state at
http://techhouse.org/~dfeuer/i915_error_state to (hopefully) allow
this message to go through.

The relevant syslog bit:

Note:

I got these two incidents running supertuxkart, which is my favorite
way to generate drm crashes. fgfs (flight sim) and blender (3d
graphics editor) are quite efficient for that too, though much less so
than in previous kernel versions.

Please file a bug report against Mesa/i965 on bugzilla.freedesktop.org.
The kernel is reporting that the userspace GL driver has caused the GPU
to execute an invalid program.
