[Bug 1311724] [NEW] Macbook Air resumes immidiately after suspend


You have been subscribed to a public bug:

Computer model : Apple Macbook Air 6,2 (Mid 2013)
BIOS version   : MBA61.88Z.0099.B04 (dmidecode -s bios-version), Oct. 2013 version
OS installed   : Ubuntu 14.04, single boot

Problem description:
When closing lid on computer machine suspends. Within 8 to 10 seconds the machine resumes again with lid still closed. Imidiately opening an closing lid makes suspends the computer and it keeps suspended until lid is opened again.

This behaviour is the same when entering a sudo pm-suspend from the
terminal. Machine suspends. But resumes after 8 to 10 seconds.
Immidiately doing a second sudo pm-suspend, suspends the machine and
keeps it suspended.

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 desribed any number
of times.

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