[Bug 1530648] [NEW] Halt command in UEFI reboots

[Goh Lip]

Public bug reported:

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.
