Looks like this is Radeon related and affects both the radeon and radeon HD drivers.
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. ** Package changed: xorg-server (Ubuntu) => xserver-xorg-video-ati (Ubuntu) ** Description changed: - Binary package hint: gnome-session + Binary package hint: xserver-xorg-video-radeon and xserver-xorg-video- + radeonhd - Latest update to Karmic busts the session manager. Filing this from the + Latest update to Karmic busts the GNOME session. Filing this from the default xterm window!
