The first 2 I had them removed during testing but I need them so I hooked them up again. They are definetely not the proble since I added them later.

The third one is probably the legacy IDE controller. There is no option to turn this of from the BIOS. Can I dissable it somehow through OS X? Maybe remove it from my DSDT?

I found the source of the issue! It sleeps if I disable Core Multiplexing! Of course this means cutting my speed to the half and it is not a solution but I think it's a very good point to start troubleshooting!

Does having to disable secondary cores give anyone any clue of what might be wrong?

I just had a little time to try all these.

I tried voodootscsync alone, SSDT alone, both of them together, I also tried dissabling SpeedStep in my bios while I tried them but no difference.

According to Chameleon my CPU Speed is 2131 but according to HWMonitor it is 2128. I tried both during SSDT Generation but no difference.

Actually, no matter what I do, even if I disable SpeedStep in the bios, I can see speedstep working: In HWMonitor my speed is altered all the time between two modes:
x6 1596MHz
x8 2128MHz

No matter what I didn't it didn't seem to make it stop changing states.

So I guess there is something else that overrides what I set...

Also using flag cpus=1 does not help. The only thing that makes it possible is disabling Core Multiplexing which makes it look like just one processor (when I used cpus=1 I noticed I had 2 processors but the second one was set to 0 MHz and that didn't help).

Yes but I tried removing these options from the plist and also didn't do any difference.

Also, I installed Mountain Lion and updated to 10.8.2. I did a clean install. Nothing changed. If I dissable Core Multiplexing sleep works! With it enabled it freezes.

Should I start a new topic now that we found the source of the problem? I see nobody is answering.. Maybe if its clear from the title that "core multiplexing" breaks sleep function more people could help me?
