Kernel Version: 3.14
Hardware: x86-64

Tree: Mainline
Status: NEW
Severity: normal

Revert commits 671cc68-c14ced0
Changes related to ACPICA that have been integrated in 3.14 break boot for some
socket 1150/1155 motherboards. Archlinux (pretty much vanilla) kernel fails to
boot after decompressing the image on select hardware.
This is probably related to BIOS issues as well as discussed in [1].
Non exhaustive affected hardware list:
Gigabyte B85-HD3
Gigabyte B85M-D3H
Gigabyte Z87P-D3
Gigabyte Z87X
Gigabyte Z87-HD3
Supermicro X9SAE-V
First problematic commit is 671cc68 [2]. Reverting commits 671cc68-c14ced0
makes booting possible again. Attached is the (crude) reverting patch against
tag v3.14.
