I experience this very same bug since let's say September 2009.

I own an HD4770 and I'm using all the graphic stack from git (drm-radeon-testing branch for the kernel).

This problem arises almost immediately when activating DFS or UTS.

Also, the command checker says in my dmesg that my userspace space is either too old or broken.

I'm free to try any patch this week.
