Title:
  Computer started to reboot instead of shutdown after kernel update

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This was originally a question, I've been suggested to file a bug.
  I'll try to give a technical account of what is happening but I am not
  familiar with developing software.

  I am running Ubuntu 12.04 64bit with Gnome 3 on a dual boot machine.
  Upon shutdown (from the menu) the computer stops, including all the
  fans but starts by itself after about 2 seconds.

  This started  happening after an update that changed the kernel from
  3.8.0-33 to 3.8.0-34. I can choose a previous kernel from the GRUB
  menu at startup and boot with 3.8.0-33 and this way I can shutdown the
  computer. I can also shutdown the computer with no problem when I boot
  into Windows. Today there was another kernel update, which I did and
  can report that the unwanted behavior continues also with 3.8.0-35.

  Things I've done:

  - Checked the BIOS for settings that might prevent computer from
  powering off. No "wake on LAN" or other settings like this are active.
  The mainboard is based on an Intel H87 chipset.

  - Added "acpi=noirq" to GRUB - no effect. If it brings any relevance:
  I recently upgraded my video card and the issue persists with the new
  card.
