So that's a 4.2 kernel which seems to be using ACPI.
Presumably this is backported, or something.
(BTW, note "EFI v2.40 by American Megatrends". I think that the people
who've installed UEFI on their MP30-AR0 boards (which shipped with only
U-Boot) have installed the open-source TianoCore. This is presumably
something different. Its predominant characteristic for me is how
extraordinarily slow it is; it takes 3 minutes from powering on to
showing the Gigabyte logo, and another minute to show a boot logo. It's
as if it's interpreting x86 code, or running from a serial ROM, or
something.)
Cheers, Phil.
