@NghiaDev ... Kernel wasnt updated in the update from 10.6 to 10.6.1 (Kernel Version was 10.0.0) but the new update to 10.6.2 contains a new Kernel (version 10.2.0). Also this new Kernel wont work with most of the Extensions that some of us have installed (like SleepEnabler or the modified AppleHDA extension).

Edit.. just found a new compatible SleepEnabler.kext here

works fine here, all i had to do was reinstall my sound kexts (alc888)

Works fine here too :)
It seems i cannot load the AtherosFix.kext somehow...

cheers

Update went very painfull here.... :(

I am no longer able to boot into 64-Bit Kernel with having my EFI String applied - otherwise every little action will drive me into a Kernel Panic, caused by com.apple.Geforce - 32-Bit Kernel & Extensions still works...

My Audio Legacy kexts are no longer working also, so I tried to replace AppleHDA.kext with the old one what made it even worse...

Guess I won't find any sleep till day is dawning.^^

Edit:
OK the second one is fixed - old AppleHDA wasn't installed properly.
But still not luck with x86_64 Kernel boot so far... Guess I'll have to try a clean installation, :-/

Thanks everyone, Finally I got 10.6.2 working, I backup mach_kernel (my specs have old CPU, I do not have Intel Core 2), and restore after install update then reboot No sound So I installed THE SAME VERSION of HDAEnabler and AppleHDA with my SL 10.6.x and my sound is enable :D Hope that the update would fix most problems og Hackintosh PCs:D

It's unfortunate that I'm having a very similar problem with geforce kp
It would be great if I was able to boot in 32bit mode. (mac server)
hope someone could shed some light cause I've tried everything from nvkexts to dsdt.:(

tried efi?

i7 860 now Vanilla
 

FYI to all P55 i7 860 (and probably i5 as well) users the new Vanilla Kernel works native now!! Boots into 64-bit mode and everything seems to be working flawlessly (have yet to try sleep).
Also, anyone out there get sound working for ACL888 on GA-P55-UD3R (S/PDIF and line out)? Sound works great in 10.5.8 with ACL888 kexts but no go for 10.6.X.

that was my original setup

nvinject stops the kp but the you get a performance hit
sluggish, stuttering
and no vlc or dvd video :(

I've just updated successful, thanks !
