dmesg log

Just got this bug and GPU lockup while trying to play Guild Wars through wine.
Happens when I rotate camera at the start of the game extensively, forcing Mesa
to compile all the shaders at once.

It's repeatable so I can provide some logs here.

Radeon R9 270

Arch x86_64, Linux 4.2.1, brand new Mesa 11.0.1
