The workaround in #4 works for me as long as I do (as root):
 "echo medium_power > /sys/class/scsi_host/host0/link_power_management_policy"

Title:
  Macbook Air resumes immidiately after suspend

Status in “pm-utils” package in Ubuntu:
  Confirmed

Bug description:
  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.
