Radeon R7 240 GPU Lockup, Ring 0 Stalled

[Esben Stien]

I was running the Xonotic game and the gpu locked up. I have compiled
the radeon driver inside the kernel.

04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240]
Linux quasar 3.16.0-rc3 #1 SMP PREEMPT Thu Jul 3 19:42:11 CEST 2014 i686 GNU/Linux
I'm running mesa git from today
xf86-video-ati-7.4

Any pointers as to what I can try?
