hit or miss sleep issue (SL 10.6.1)

[NoValidTitle]

I'll start off saying I tried to search but the site errors out when I try to search for sleep.

 

Hardware:

 

Asus Maximus Formula mobo

Q6600

8GB Crucial Ram

GTX 285

WD 300GB Velociraptor HD

 

Snow Leopard running 10.6.1

 

I'm running an untouched retail install with chameleon RC3 installed on my EFI partition with all kexts also on the EFI partition.

 

I do have a patched dsdt that someone posted on a site somewhere, I could find the link if someone needs to see that.

 

I'm also running the SleepEnabler.kext.

 

Now the actual problem... sleep DOES work, but not always. About 50% of the time when I put the computer to sleep the display shuts down but the computer is still on, fans spinning, LEDs on etc etc. When it gets in that state the only way to get it out is power the box off holding in the power button. When it DOES goto sleep just fine, it wakes up just fine. But it wont always sleep for some reason. Any ideas?
