I'm trying to build the 2.6.18 kernel for a Intel Core 2 Duo 2.4GHZ in a 
Asus P5W DH Deluxe Motherboard which has a 975 chip set. It does work 
when booting from a 2.6.15-27 kernel installed from Ubuntu 2.06 LTS.

When failing I get three messages on the screen:

PCI: BIOS Bug: MCFG area at f0000000 is not E820-reserved
PCI: Not using MMCONFIG
Intel-rng: FWH not detected

The first two appear to be from lines 215 & 217 of mmconfig.c (x86_64)
and the other is from line 313 of intel-rng.c.

Attached is my config file, I've tried both Generic-X86-64 and Intel 
EM64T for the Processor family.

Thanks,

Wink Saville
