shiro - can you tell the bios version on your machine? 
Assuming that this might be duplicate on bug 97621
Comment 2 shiro 2016-11-11 17:06:18 UTC
BIOS Information:
  Bios Version     0215 x64
  Build Date       04/18/2016
  ME FW Version    11.0.0.1168
  Stepping         31/D1
Comment 3 shiro 2016-11-11 17:50:36 UTC
Updated to BIOS version 2002, problem is still here.
Comment 4 shiro 2016-11-17 12:49:05 UTC
Tried format partition as UEFI instead BIOS and after installing Arch Linux same error happens.

Cat /proc/iomem pls for an offending machine, plus dmesg.
Comment 7 Daniel Vetter 2017-07-18 08:46:08 UTC
Reopening just for CI so we can do a hack for CI machines, not going to solve this in general.
