Macbook Air resumes immediately after suspend

[David Cubero]

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.

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.
