Since at least a month, my 11.10-64bit PC doesn't shutdown anymore from the GUI. It simply freezes on plymouth screen. If I open gnome-terminal and type "sudo poweroff", it shuts down correctly.

This is very annoying. I don't have any relevant message in the logs. It simply stops at "The system will be halted"...but it doesn't power off.

Then it hangs there, not powering off. - if I type "sudo halt -p", the system powers down correclty until it shuts off. – Fabio Feb 26 '12 at 12:26

Actually if you want to shutdown and power off the machine, you should type:

sudo shutdown -P now

-h:     Requests  that  the system be either halted or powered off after
        it has been brought down, with the choice as to which left up to
        the system.

-P:     Requests that the system  be  powered  off  after  it  has  been
        brought down.
