[Launchpad Bug Tracker <1507472@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

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
