Title:
  Computer does not power off when attempting to shut down by any route.

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Computer does not shut down, but instead merely freezes at the
  graphical splash screen while remaining powered on, with monitor,
  fans, and all other hardware still running. I've attempted the
  following, all with no success:

  - Issuing halt, poweroff, halt -P, shutdown -h/-H/-P, and every other
  conceivable variation thereof from a terminal. Have also attempted
  these commands from a tty after killing X.

  - Graphical shutdown from unity panel. Have also tried this at login
  screen.

  - Have attempted to disable various services and kernel modules that
  have been implicated in other bug reports complaining of similar
  issues (namely, laptop-mode, acpi-support, proprietary fglrx driver,
  networking, and misc. others).

  - Various suggestions from Ubuntu forums (editing /etc/default/halt,
  updating grub with various different arguments to
  GRUB_CMDLINE_LINUX_DEFAULT, disabling network-manager service prior to
  attempting shut down, and others).

  This shut down malfunction happens invariably and with total
  predictability. Oddly, rebooting does initially appear to work, but
  when computer powers back on, the OS fails to load and instead hangs
  at a blank, purple screen (without the typical Ubuntu logo).

  Other relevant info:

  - Computer is an Acer Aspire 5560-7402 laptop.

  - Ubuntu is the sole OS, installed recently with default/automatic
  partitioning settings, using whole disk.

  - uname -srvmpio output:
  Linux 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux (please note that the problem began immediately after installation, i.e., before upgrade from 3.2.0-23-generic kernel).
