Title:
  Ubuntu hangs on Shutdown and Reboot

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I know this has been reported before and on one such report the status
  seems to show bug Fixed but today is 16/4/12 and i have just applied
  the latest updates to Ubuntu 12.04 beta 2 and the bug still persists
  for me. Basically, when i shutdown or reboot, the screen goes black
  but you can hear the fan running. It stays this way until I press the
  power button for about 7secs or so.

  My own investigation shows that when I log in and don't open any programs and I shutdown or reboot it works fine. Its when I perform my normal work on the system and try to shutdown or reboot then it hangs. Also I noticed that on the occassions that it fails to shutdown or reboot, I don't see the ubuntu name with the animated dots underneath. I am prepared to perform any test and report back to you if you help me.  This seems to still be a problem for many and a quick google search will show.
