Subject: 2.6.36 oops in intel_ring_advance() (i915/DRM) when running opengl programs

Hello,

I tested 2.6.36 on an Asus laptop with an Intel GM965 chipset. I first
noticed the oops when i tried to run Virtualbox, which links to
opengl, and i tried reproducing it with glxgears, which it
consistently does.

I also noticed an earlier email on this oops, from august 16, 2010,
that didn't get any replies.
