Christopher,

with 3.18-vivid (3.18.0-031800_3.18.0-031800.201412071935):

The good news is that thunderbold-ethernet is plug and play (no longer
needs to reboot with thunderbold plugged in). Unplugging it and plugging
it again works too: fully plug and play.

The bad news is that the computer cannot suspend at all:

A. When using the top-right power button and choosing suspend, the screen goes dark but quickly brightens.
B. When closing the lid, the screen remains dark but it is actually not suspended (can been seen in dmesg).

All 4 CPUs are recognized after the first reboot--but this was the case
before too. Don't know what will happen in the next reboot.

The dmesg (attached) contains, in this order, the normal boot sequence,
one attempt to suspend from the power menu, and one attempt to suspend
by closing the lid, and the plug-and-play action of the thunderbold-
ethernet adapter.

The relevant part of dmesg from the point in time when I initiated the
suspend sequence by lowering the lid (notice the ERROR):

Title:
  [MacBookPro11,1] Unable to suspend in ubuntu 14.04

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I cannot make a MacBookPro 11,1 suspend. When putting the lid down, acpi_listen prints:
  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.

  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.

  To remark that the power menu in the System Settings shows sometimes
  "Suspend" as greyed out.
