Could be quite easy to bisect, cause previous state of mesa 9.1 git
I compiled didnĀ“t have these hangs. I am right now using mesa 9.1
branch as of 1e043ebe034b6e33b4c5228770db397b22fd26e0.

Kernel is 3.9.

Ok, I bisected this meanwhile:

martin@merkaba:~/Spielen/Mesa/mesa.git> git bisect good
9f66038b5bac7f3574a00beda850be31712f9610 is the first bad commit
commit 9f66038b5bac7f3574a00beda850be31712f9610
Author: Kenneth Graunke <kenn...@whitecape.org>
Date:   Mon Apr 22 23:13:47 2013 -0700

     mesa: Add an unpack function for ARGB2101010_UINT.

     v2: Remove extra parenthesis (suggested by Brian).

     NOTE: This is a candidate for stable branches.

That's odd. I didn't think PlaneShift used ARGB2101010_UINT. It looks like CS may have support for it though, so I guess it's possible...

I'm still a bit skeptical of the bisect though.
