--- Comment #9 from Stanisław Halik sthalik@misaki.pl --- Last I know Hyper-Z was disabled due to few cases like this, and can be re-enabled through the `SB_DEBUG' environment variable. It would be interesting to see if r600 gallium-nine also exercises the freeze. The original freeze happened using Wine's d3d9 -> opengl translation.
Sadly I cannot make a new trace as that 6970 gave up the ghost.
