[Bug 490742] Re: MacBook Pro: very slow resume from S3 suspend-to-ram

 

For me, it still takes about 20+ seconds to resume, i.e. before the
backlight comes on again. Attached is a snippet of my dmesg, showing one
sleep cycle. I'm on kernel 2.6.32-24...

MacBook Pro: very slow resume from S3 suspend-to-ram

Bug description:
I tried: 
  User switching menu -> Suspend
  sudo /etc/acpi/sleep.sh force
  echo mem | sudo tee -a /sys/power/state
In all of these cases, it takes over 20 seconds to wake up the devices. I tried removing a couple of modules that seemed to be possible culprits, but that did not help. At this point I don't know how to debug this further.

This is a regression, since resume was quite zippy in 9.04.

Help?
