Title:
  MBP 8,1 fails to boot without noefi since linux-
  image-3.13.0-20-generic

Status in “linux” package in Ubuntu:
  Confirmed

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, unless the noefi kernel
  param is set.

  When booting linux-image-3.13.0-20-generic or later without the noefi
  param, I get a grey rectangle displayed, centred, filling most of the
  screen, and the system hangs. If booting into rescue mode without
  noefi (i.e. without quiet, splash, vt.redirect, etc.), I see the
  following (roughly, from memory...)

  > Loading vmlinuz-3.13.0-27-generic...
  > Loading initrd.img-3.13.0-27-generic...

  Then the system hangs. In either case, on reboot I'm dropped
  automatically into the GRUB menu.

  To boot in EFI mode, I keep linux-image-3.13.0-19-generic around -
  which works fine. Booting a latter kernel works if I specify noefi,
  however gfx and disk performance suffers, and features such as the
  monitor brightness keys fail to work altogether.
