Have you had a look in the logs to see if anything is there (System >
Administration > Log File Viewer)

Do you get a terminal window if you enter Ctrl Alt F1  (Ctrl Alt F7
should take you back).  If you do then at least you can login and
restart with
sudo shutdown -h now

Has anyone else any ideas?   Otherwise I think you may have to submit a bug.
