Well, we've quite massively tuned our gpu address space handling in 3.5, so it's a bit more likely to hit this problem. Relevant commits are 3ae5378330f5814 ffc62976d2158 dabdfe021ab1e985e > So please please *please* take a second look.

Nope, and you've reported this exact problem previously already, e.g. http://comments.gmane.org/gmane.comp.video.dri.devel/63082 Really, please upgrade your userspace - this is by far not the only bug fixed since then that can result in a gpu hang.
