[Bug 1530648] Re: Halt command in UEFI reboots

[Goh Lip]

Thanks. Tested 2.02~beta2-35 and confirm halt works in uefi.
Also in bios-legacy, halt command works completely to shutdown.
Prior to this, in bios-legacy, 'halt' hangs and does not reboot.

So confirm this update fixes both uefi and bios-legacy to complete
computer shutdown.

Title:
  Halt command in UEFI reboots

Status in grub2 package in Ubuntu:
  Fix Released

Bug description:
  Issuing "halt" command in grub prompt reboots the computer instead of
  shutting down completely. This happens only in UEFI systems and not in
  bios-legacy which works as it should. Computer does power down but
  restarts again.

  Also, this happens in some mother boards but not others.
  Affects the following Ubuntu grub versions - (all current) but tested on
  Kubuntu Xenial - 2.02-beta2-32ubuntu1
  Kubuntu Wily   - 2.02-beta2-29ubuntu0.2 

  Machine tested is..
  Machine: Mobo: ASUSTeK model: P8B75-V v: Rev X.0x
  Bios: American Megatrends v: 0414 date: 04/24/2012 

  There is a fix for this in
  http://git.savannah.gnu.org/cgit/grub.git/commit/?id=aa7bb4607bb799b2790ea008bcfd8d6ca0a6d752

  Would appreciate if Ubuntu update its grub version.
  Thanks.
