[Bug 975867] [NEW] /sbin/halt fails to halt system

[Gerben]

Public bug reported:

issuing the halt commando (e.g. halt as root) will not switch off the
computer. All services will be stopped, a final ¨ * Will now halt"is
posted on the console (a desktop installation), but the computer does
not switch off. Either it needs to be switched off at the machine
(physical machine) or a "Fore off"needs to be performed (kvm virtual)
needs to be performed.

This happens when /sbin/halt is used.
When the (unity?) menu "Shut Down..." is used, the machine switches off as expected (either shut down from login-console when not logged on, or from (unity?) menu when logged on).

/sbin/reboot reboots the machine correctly.

See attached screenshot for graphical output.
