--- Comment #16 from Hamish Wilson hamish@icculus.org --- 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.
