Title:
  MacBookPro 11,1 (Haswell, retina) fails to both suspend and hibernate
  with ubuntu 14.04

Status in “pm-utils” package in Ubuntu:
  Confirmed

Bug description:
  Cannot make a MacBookPro 11,1 suspend.

  1. When putting the lid down, acpi_listen prints:

  $ acpi_listen 
  button/lid LID close
  button/lid LID open

  ... so the lid is signalling correctly. Upon opening, the screensaver
  prompt is present, and typing in the password brings me back to the
  desktop. Nothing is found in dmesg.

  2. When choosing "suspend" from the top-right power menu, the screen
  goes black and shortly lights up again, showing the screensaver login
  prompt. Typing in the password brings me back to the desktop as if
  nothing had happened.

  3. To remark that the power menu in the System Settings shows
  sometimes "Suspend" as greyed out, and hibernate is not listed.
  Perhaps this is related to the suspend process taking very long
  (minutes) as reported in other bugs, but I have never waited so long
  to find out.

  4. When attempting to hibernate instead, using:

  $ sudo pm-hibernate

  ... something similar to triggering a suspend happens, but this time
  dmesg lists one error:

  
  [ 1434.487141] [drm:hsw_unclaimed_reg_clear] *ERROR* Unknown unclaimed register before writing to 2030

  The whole relevant part of the dmesg is below, containing the sequence
  towards hibernation and then the sequence towards power up, cropped at
  the CPUs.

  Any hints towards getting suspend or hibernate working would be very appreciated.
