Title:
  [MacBookPro8,1] Fails to boot without noefi since linux-
  image-3.13.0-20-generic

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  My MacBookPro 8,1 (Early 2011, 13") will not boot using any trusty kernel linux-image-3.13.0-20-generic or later. I get a grey rectangle displayed, centred, filling most of the screen, and the system hangs. When booting into rescue mode without kernel parameters quiet, splash, vt.redirect, etc., I would see something like:
  > Loading vmlinuz-3.13.0-27-generic...
  > Loading initrd.img-3.13.0-27-generic...

  Then the system hangs. When I reboot I'm dropped into the GRUB menu.
  To boot in EFI mode, I keep linux-image-3.13.0-19-generic around - which works fine.

  WORKAROUND: Booting using kernel boot parameter noefi, however gfx and
  disk performance suffers, and features such as the monitor brightness
  keys fail to work altogether.
