Try removing IOPCIFamily.kext under Fixes and Patches if you have it selected. That did it for me (also had the Apple ACPIPCI and Still waiting .....)
So this is post 311 of the iPC Universal Final Release thread on insanely mac forums.
And low and behold that was the result of the last installation... try again... onto 5th install...
Same as fourth Installation, just without the IOPCIFamily.kext patched "Fix". Hope that unfixes the roadblock of getting a stable Hack`
So that'll continue installing into today... it's Monday now. Nitez all.
