[Bug 70411] 7970M PRIME: lockup with Distance game, recovery doesn't work

https://bugzilla.kernel.org/show_bug.cgi?id=70411

--- Comment #3 from Christoph Haag haagch.christoph@googlemail.com --- Maybe it would have been good to mention, mesa is a relatively current git version a21552a.

(In reply to Michel Dänzer from comment #2)

Does setting the environment variable R600_DEBUG=nohyperz for running the game work around the problem?

Yes, with R600_DEBUG=nohyperz the game works and there is no lockup.

I guess it's possible that it stopped working when HyperZ was enabled by default.

Still, this lockup is not nice since currently only a reboot makes the radeon gpu usable again.
