--- Comment #25 from Alexandre Demers alexandre.f.demers@gmail.com 2012-02-21 20:25:39 PST --- Does this imply that when not using 2d tiling it shouldn't crash or lock anymore or is it specific to 2d tiling usage?

(In reply to comment #24)

I pushed a mesa fix for bo allocation issue. If you enable 2d tiling properly you shouldn't have lockup anymore. There is also a kernel patch to fix kernel issue after gpu lockup.

To properly enabled 2d tiling you need libdrm from git and ddx from git and add:

Option "ColorTiling2D" "true"

To your gpu device section of xorg configuration
