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?

Changing the extension is not the answer. The dsl file is the source code. To turn it into aml you have to compile it. Open it with a DSDT editor, compile it and save the aml file.

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.

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).

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?
