I restarted it a few more times (without radeon.modeset=0) to see if any other bizzare things would happen. Twice, I got to the screen with an underscore in the corner, but it had a (moveable) mouse cursor in the middle. Doing Ctrl-Alt-F1 got me to a text terminal. Switching back to Xorg with Ctrl-Alt-F7 got me to my desktop. I started up Firefox to get to Launchpad, and the computer then stopped responding to keyboard and mouse input. Had to use magic SysRq keys to shutdown. Xorg log is attached.
