Guys, please use minimum extra kexts as possible ( for example do not use SleepEnabler.kext - this might cause kernel panic, sometimes, even for Vanilla kernel )

Backup your current working kernel ( mach_kernel or legacy kernel ) and replaced by mach_kernel from the zip file

Delete all /System/Library/Caches/*
Delete all /Library/Caches/*
Delete /Extra/Extentions.mkext
Use Disk Utility to fix all permission

Boot with these options for the first time
-v -f arch=x86_64 -x64 -force64 ( put all, it's better to give more than missing something )

After that you can boot without -f
