Field Note #1 @maruchan 2009-08-12

Yes, this is a universal problem. 10.5.8 broke everyone's sleep, as far as I know. Pista7 at Insanelymac posted this expanation today:

The reason for the 10.5.8 sleep problems is, that there is a small piece of code added to the new kernel, that tries to shut down all CPUs (except the one running the go-to-sleep code of course when going to sleep. This is implemented by calling the registered PM extension (AppleIntelCPUPowerManagement under normal circumstances) and…

In the meantime, there are a number of workarounds available. The simplest is to use DSDT Patcher to create a dsdt.aml with "Force HPET" checked, and then remove Disabler.kext, NullCPUPowerManagement.kext, or any other disablers from your system. Your CPU will run about 8 degrees hotter, but sleep will be fully functional.

Thanks, I went for the simple option and installed sleepEnabler.kext, but thanks for the info. It's nice to know what's causing the problems.

I've included the kext in case anyone reads this and has the same problem.
