--- Comment #1 from Marek Olšák maraeo@gmail.com 2010-07-12 19:19:28 PDT --- [My comment from Bug 29020, which seems to be the same issue as yours]
Multiple simultaneously running contexts are most probably the cause of these hardlocks, because this way the driver may generate pretty much a random command stream which has valid register writes, meaning that the CS checker doesn't notice anything, and the hardware goes crazy.
Wine uses multiple contexts quite often, if not all the time.
Soon I am going to rewrite winsys for it to support multiple command streams, and then we'll see if it resolves this issue...

This time the machine didn't hang, but the screen went off. I had to reboot to bring it on again. Attached kernel output.

--- Comment #6 from Maciej Cencora m.cencora@gmail.com 2010-09-11 05:50:26 PDT --- It doesn't hang anymore with mesa afd328afa8fdad58d22c214c01bcbf82614801c5.
Unfortunately the image is broken, and the game is unusable under r300g. Works fine with r300c though.
