Title:
  XHCI controller causing MacbookPro12,1 to resume immediately after
  suspend

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On my MacbookPro12,1 with Wily and Linux 4.2, by default the kernel
  successfully suspends but then immediately resumes again. The problem
  seems to be the XHCI controller causing spurious ACPI wakeups.

  Also, the Broadcom wifi module seems to have problems with
  suspend/resume, so I am also unloading the `brcmfmac` module prior to
  suspend and loading it again after resume.

  WORKAROUND: Disable XHC1 prior to sleeping:
  > # echo XHC1 > /proc/acpi/wakeup
