[Bug 359392] Re: [i965] X freezes starting on April 3rd

[JesseBarnes]

I still haven't been able to reproduce this.  I did notice that Albert,
Dustin and Bryce's intel_gpu_dump output was identical though (all had
what looked like i965 render commands in them).  Some people have
reported that using EXA greedy migration made the bug go away, I wonder
if disabling render accel altogether would as well (ExaNoComposite true
in xorg.conf)?  Can someone who's seeing this frequently give that a
try?

So far the closest I've come to seeing this with Jaunty is by starting
50 instances of glxgears.  That makes X pretty much unusable (all my
windows grey out and no other rendering seems possible).  That's pretty
pathological though, so probably isn't the problem, though it does
indicate some issues with our GPU scheduler under high load.
