[Bug 880240] Re: ubuntu 11.10 : the system doesn't turn off if "sudo halt" is given

[Viswanath]

Just installed 11.10 and I am having the same problem with shutting down. The only way to halt the system is to press the power button physically.
If memory serves, it started after I did an update today (Mar 02, 2012).

DELL Studio 1558
Dual booting Ubuntu 11.10 (x64) & WIN 7 (x64)

Title:
  ubuntu 11.10 : the system doesn't turn off if "sudo halt" is given

Status in “upstart” package in Ubuntu:
  Confirmed

Bug description:
  Since I upgraded from 11.04 to 11.10 the system doesn't turn off at
  the end of halt procedure if it's called via commandline (local or
  remote shell) . At some point of halt procedure the system freezes and
  all I can do is turning off pc via physical power button and halting
  it using GUI or via "sudo shutdown -h now" , these two methods work
  flawlessly.

   I have this problem on both x86_64 and x86. Anyway if I shut down the
  pc using ligthdm or unity the system is turned off properly.
