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

[Tipi Koivisto]

When I do "shutdown -r 0" as root boot is executed nicely. Says "*Will
now reboot" and reboots.

On the other hand when I do "shutdown 0" as root the last message in
standard output is "*Will now halt..." and then comes Mr. Freeze. I can
even hear the hardrive shutting down but then it just freezes.
"poweroff" (with any option) gives the same result. Executing "poweroff
-f" the screen freezes instantly after printing "Powering off".

Therefore I think the problem is in somewhere between Halt / Poweroff
and hardware.

At the moment with Lenovo S205 Ideapad and 11.10 the only way to
shutdown seems to be is by pressing power button.

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.

  Description:	Ubuntu 11.10

  Linux travelmate 3.0.0-13-generic #21-Ubuntu SMP Mon Oct 17 20:18:09 UTC 2011 i686 i686 i386 GNU/Linux
