I'm having trouble with the game Wasteland 2 Directors Cut.

It sporadically freezes (most often when loading new areas) sometimes right away after starting a new game sometimes after several hours of gameplay. 

I'm getting a massive log of VM fault, GPU_fault_detected as soon as the game is launched.

#98183 and #98619 seems similar.

Probably not a regression, it's present with 4.7.0 and Mesa 12.

I also tried recording with apitrace, the trace itself doesn't seem to trigger the VM fault stuff, but I do get these warnings:
