Hi Christopher,

I installed 3.18-vivid from http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.18-vivid/, and the results are concerning:

First I rebooted and booted fine into 3.18. I run "uname -a" just to be
sure, and listed 3.18 as the current kernel.

Of course I didn't have wifi with 3.18, so I wanted to reboot to go back
to 3.13.43. Upon reboot I pushed "del" to make grub show its menu, chose
3.43 and then it got stuck with a blinking cursor.

So I shut down the machine, booted again and letting it go into 3.18:
this time it dit NOT boot, to my surprise. I would appreciate help in
understanding what had changed.

Upon reboot using the "failsafe" option, I saw that the booting process
got stuck at SMP #1. So I shutdown, rebooted and edited the grub kernel
options to include the "nosmp" flag, and that booted into 3.18 just fine
--from which I am writing this (via USB-ethernet).

Haven't tested yet if the thunderbolt ethernet and suspend work.

Before I engage into further reboots that could get stuck, I would
appreciate assistance in understanding why the second time 3.18 needed
the "nosmp" flag, and how can this be addressed.

Additionally I would appreciate help in understanding why grub cannot
boot the old 3.13.43 kernel when chosen from the grub menu. I recall
this issue when I first installed Ubuntu into thhis macbook pro 11,1:
only the default menu option would boot from grub; choosing from the
list of available kernels did not work, likely because of the SMP issue.

Thanks in advance for your insight.

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.
