The kernel says '[drm] nouveau 0000:01:00.0: validate: -85' when this happens,
because ttm_bo_wait_cpu() is returning -ERESTART. If I convert that to
returning -EINTR, it just goes into an endless loop calling it over and over
again instead of aborting.
This is a MacBook Pro with GeForce 8600M GT
Running current packages from Fedora 12 rawhide.
