I've been seeing occasional hard locking of X when I change the size of my video player from windowed to full screen or from full screen to windowed. Here's my setup:

Debian Squeeze AMD64
Kernel 2.6.30-rc5 (self compiled)
Xorg 7.4 (self-compiled)
Gnome 2.26.1 (debian packages)
Totem 2.26.2 (debian package)
radeonhd (I git pull every 2-3 days.)
drm (native, built into kernel 2.6.30)

Two 1920x1200 panels over DVI
DVI-I_1/digital is Left Panel
DVI-I_2/digital is Right Panel

I've been using randr to disable the left monitor when I watch videos. This seems to be a necessary condition for the bug. I see the bug when running totem on the remaining right display. X locks hard when totem transitions between full screen and windowed mode. It happens on both directions. All keyboard input is ignored. I have to ssh in and kill X. It's always at 100% cpu utilization.

This doesn't happen on every transition between windowed and full screen but it happens often enough.

I've been using the power switch to disable my left monitor. I want to verify that the bug happens only when randr is used to disable the left screen. It has been proven true so far.

I have tried the "radeon-test-ring.patch" from Bug 21849. It didn't help. The logs attached were produced wile running a kernel with that patch.
