[Bug 1311724] Re: Macbook Air resumes immidiately after suspend

[Maarten Verwijs]

I'm experiencing the same problem.

- First suspend after reboot works every time without fail.
- Second suspend does a resume after 3 or 4 seconds. 

The workaround ( sudo pm-suspend; sudo pm-suspend) only works on my
Macbook Air 6,2 when I've applied the workaround for this bug:

Workaround: 
echo min_power > /sys/class/scsi_host/host0/link_power_management_policy

In order to have my macbook air suspend everytime I close the lid I've
added this line to /usr/sbin/pm-suspend:


$ diff -p pm-suspend.distrib pm-suspend
*** pm-suspend.distrib	2013-11-06 17:26:04.000000000 +0100
--- pm-suspend	2014-06-26 14:06:18.672660848 +0200
*************** if run_hooks sleep "$ACTION $METHOD"; th
*** 101,106 ****
--- 101,107 ----
  	log "$(date): performing $METHOD"
  	sync
  	"do_$METHOD" || r=128
+ 	"do_$METHOD" || r=128
  	log "$(date): Awake."
  else
  	log "$(date): Inhibit found, will not perform $METHOD"

Also do a "dpkg-redirect add /usr/sbin/pm-suspend" to prevent the change
from getting overwritten.
