Subject: [i915] 2.6.36-rc4-git2 (Fedora snapshot) - kernel BUG at drivers/gpu/drm/i915/i915_gem.c:1444!

Hello,

I've been hitting this repeatedly in using this kernel this is a recent issue. Also, www.kerneloops.org seems broken, someone might want to fix this? We can disregard virtualbox drivers causing this especially given the 
traceback.

trace below:
