[Bryce Harrington <757141@xxxxxxxxxxxxxxxxxx>]

Thanks for the photos.  Yeah looks like the compiz process triggered a
page fault in the radeon drm module which caused a kernel OOPS.

IMG_0686 has the clearest call trace.  I'll add that to the bug
description.

IMG_0689 shows the top of the oops report pretty clearly.

** Description changed:

  Binary package hint: xorg
  
  I booted a LiveUSB of the current natty daily ISO. It got to the screen
  where it asks whether I want to Try or Install Ubuntu. I selected "Try".
  It switched back to the console, then loaded xorg with a cursor in the
  center of the screen and a black background and stopped. I could move
  the cursor around with my mouse, but Ctrl-Alt-F1 didn't do anything. I
  eventually did Alt-Sysrq-R and Alt-Sysrq-K to restart xorg, logged in on
  gdm, and got to a normal desktop.
