Public bug reported:

A regression in 12.10 has caused unreliable suspend/resume on my
MacbookPro 3,1. Under 12.04 the machine would reliably enter suspend.
Under 12.10, the machine will enter suspend correctly in about 1 of
every 4 attempts. Usually the machine will appear to enter suspend then
immediately wake back up.

To reproduce:
1) Choose "suspend" from the power menu

Expected results:
The machine enters suspend every time and stays suspended

Actual results:
Usually (about 3 of 4 times) the machine will enter suspend then immediately 
(within 1 second) resume from suspend to a prompt.

This is a regression from 12.04, which was generally reliably on the
same machine.

I tried the 3.6.3 kernel from http://kernel.ubuntu.com/~kernel-
ppa/mainline/ ; it did not fix the problem.
