Xorg hangs with drmwtq in 7.2-RELEASE

[David Johnson]

After much rebuilding and testing, I have narrowed down the introduction of 
this bug to commit #189855. Most of this commit is related to r600/700 chips, 
but there are other changes. I don't understand the code and can't see 
anything obvious. But it is a place to start.

Does this help any? Or should I keep banging my head against the wall?
