dmesg output

When trying out Kerbal Space Program for linux (version 0.19 was just released
with native linux support) I get GPU lockups when constructing rockets.

Everything worked well at first, but after a few minutes I got the first GPU
lockup and after that it seem to lock up every 5 seconds or so, so I had to
kill the game.

This happens every time I run the game. MSAA and vsync were not enabled.

I'm running mesa from git: 
Mesa 9.2.0 (git-2da8ee1) on a Radeon HD 5670

and the arch linxu kernel: 
Linux none 3.8.3-2-ARCH #1 SMP PREEMPT Sun Mar 17 13:04:22 CET 2013 x86_64
GNU/Linux

I've attached a full dmesg log.

I'm running KDE and have two monitors set up. The lockups happened both with
and without desktop effects enabled.
