intel DP55WB / i7 860.

I successfully patched dsdt with all regular fixes.
AppleLPC loads by default.
If I remove nullcpu from /extra I get a kp regarding appleintelcpupowermanagement.

I cannt find the reason for this. I have done this before with my q6600.
rc4-aserebln-1.1.9 / 64bits / fakesmc.kext in extra. imac 11,1 in smbios.
Tried anval cham. build too.
thanks in advance for -any- light on this.

edit: solved. update bios 'till 144 build. anything newer => kp. Thanks spíder for the hint.
