*SOLVED* 10.8.2 only works with VT-d disabled

Hi,

clean installed 10.8.2 successfully on GA-P67A-UD3-B3 /w i7-2600 after disabling vt-d in uefi.
My 6850's performance halfed in WoW and Diablo 3 and i am without vanderpool-d support. Not good!
Did Apple change something in their sandboxing-code, so that 10.8.2 gets incompatible with vt-d on my setup?

Any ideas how to resolve those issues?

To be able to run 10.8.2 with VT-d enabled, /System/Library/Extensions/AppleACPIPlatform.kext has to be replaced with the 10.8.1-version.
So just grab the kext from your backup and enjoy!

10.8.2 now runs with VT-d enabled on GA-P67A-UD3-B3 and UEFI BIOS U1a
