Requires a hard boot, KMS on.

I am aware GLSL support in Mesa git master, is still in heavy development

Another GLSL bug for you Ian.
Comment 3 Shawn Starr 2010-03-16 17:06:39 UTC 
No longer GPU hanging but the game just freezes completely, have to kill it forcefully. This is with 2.6.34-rc1.
Comment 4 Shawn Starr 2010-12-04 22:35:21 UTC 
Closing this, GLSL crashes game altogether.
