Bug still occurs with a Radeon HD 5750 on Fedora 20 x86_64 running Linux 3.12.9
and Mesa 9.2.5. Disabling HyperZ by entering "export R600_HYPERZ=0" into a
terminal before launching Brütal Legend stops the crashes.

Interestingly, it does not show up with my Radeon HD 4670 on Arch i386 running
Linux 3.12.9 and Mesa 10.0.3 - although it should be noted that the problem was
still not in evidence before I upgraded the system to the latest stable version
of Mesa.
