Watching a youtube video fullscreen with adobe flashplayer and then leaving fullscreen sometimes triggers a bug in the drm/radeon/ttm, this is with kernel 2.6.38-rc5, ddx from git and happens with both stock r600c from ubuntu 10.10 and r600g from git master.
The bug is only triggered sporadicly, but a good way to reproduce I found is to go and play a youtube video. e.g. http://www.youtube.com/watch?v=8ETDE0VGJY4 then position the mouse pointer at the bottom-right of the player where the fullscreen button is and start clicking many times as fast as you can. The player will go fullscreen and leave fullscreen a couple of times and will eventually trigger the bug.
