[Bug 1559882] Re: Macbook Air resumes immediately after suspend


On Macbook Air 7.2 (running Mate 16.04) closing lid suspends correctly
after initial boot. Sometimes works for several cycles. Usually on
second and subsequent cycles, the machine resumes again after a few
seconds, while the lid is shut. From then on, this behaviour is
consistent and does not change. Also same problem after manually placed
into suspend from power menu.

Workaraound: Disable XHC1

For example:

echo XHC1 | sudo tee /proc/acpi/wakeup   (toggles XHC1)

This completely fixes the problem, and subsequent lid close/open works
as it should.

uname -r

  Macbook Air resumes immediately after suspend

Status in linux-lts-vivid package in Ubuntu:
Status in linux-lts-xenial package in Ubuntu:

Bug description:
  When closing the lid on the computer, the machine suspends. Within 5
  to 10 seconds, the machine resumes again with lid still closed.
  Opening and closing the lid again yields the same behavior again
  (suspend and resuming after a few seconds without opening the lid).
  This behaviour is the same when entering a sudo pm-suspend from the
  terminal, or using"Suspend" from the menu.

  There is one case where the behaviour described above is different.
  That is in the situation where machine is put into suspend for the
  first time after a complete reboot. In this case the machine suspends
  correctly and stays suspended as expected.

  The problem is consistent and can be reproduced as described any
  number of times.

  Disabling wi-fi (using the Broadcom 802.11 Linux STA proprietary
  driver) doesn't alter the behaviour described above.

  cat /proc/acpi/wakeup
