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.
