Title:
  Suspend failure/crash on Macbook Air 5,2

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Until a few weeks ago suspend worked perfectly on my 2012 11" MacBook
  Air.  Since that time however it has become very unreliable.

  If I close the lid to suspend and reopen within a short period of time
  it resumes and all is fine.  If left longer eg overnight then on
  opening the lid the system is off and on power on cold boots.  last
  will show this as a crash.
