black screen of death

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.

I think this is a bug with pageflipping. Whereas I have successfully have been
able to trigger this bug all the 3 times I tried with the method mentioned
above with pageflipping enabled, so far I'm unable to reproduce this with
pageflipping disabled.

Are you using a GL compositor like compiz or kwin in GL mode?

Nope. Just plain metacity without any form of compositing.

(v2), 2011-05-29) help?

Rafael Monica, Ubuntu 10.10 reached EOL on April 10, 2012. For more on this,
please see https://wiki.ubuntu.com/Releases.

If this is reproducible with a supported release, it will help immensely if you
filed a new report with Ubuntu by ensuring you have the package xdiagnose
installed, and that you click the Yes button for attaching additional debugging
information running the following from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.

For more on why this is helpful, please see
https://wiki.ubuntu.com/ReportingBugs.
