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.
