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
