[Problem]
X server fails with DRI : drmRadeonCmdBuffer: -22

[Original Description]
Latest update to Karmic busts the GNOME session.

I see the new xsplash graphic. The cursor changes to waiting for a bit and then
I'm back to the GDM login window.  It looks like Xorg died:

gnome-settings-daemon: Fatal IO error 104 (Connection reset by peer) on X
server :0.0.
gnome-session: Fatal IO error 11 (Resource temporarily unavailable) on X server
:0.0.
-----
The application 'gnome-panel' lost its connection to the display :0.0;
most likely the X server was shut down or you killed/destroyed
the application.
XIO: fatal IO error 0 (Success) on X server ":0.0"

      after 1159 requests (1152 known processed) with 0 events remaining.

No protocol specified
Window manager error: Unable to open X display :0.0

The key issue is

drmRadeonCmdBuffer: -22

After which the X server fails. However it loads the GDM OK and will load the
xterm default succesfully.

Switching off DRI on RADEONHD and ATI allows the full gnome session to load
properly.
