Does disabling hyperz help?

I have the same Problem but it doesn't matter if DPM is enabled or not.

I can reproduce this Bug when i play on the map "Ghost Town"(Wave 666).
Always when the Tanks are comming and I going to them the GPU hangs.
On other maps its more or less random.

Every component was build yesterday
   Linux 3.14-rc1(drm-fixes branch)
   LLVM 3.5-svn
   Mesa 10.2-devel git
   xorg 1.15.0
   glamor 0.6


PS: Sorry for my bad English >_<

I think it's coincidence.  balanced and performance are the same on your chip.
