Specifically
MCFG on AMD-based Systems
During PCI probing, Red Hat Enterprise Linux 4 Update 5 attempts to use
information obtained from MCFG (memory-mapped PCI configuration space). On
AMD-systems, this type of access does not work on some buses, as the kernel
cannot parse the MCFG table.
To work around this, add the parameter pci=conf1 or pci=nommconf on the
kernel boot line in /etc/grub.conf. For example:
title Red Hat Enterprise Linux AS (2.6.9-42.0.2.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-42.0.2.EL ro root=/dev/VolGroup00/LogVol00
rhgb quiet pci=conf1
initrd /initrd-2.6.9-42.0.2.EL.img
Doing this instructs the kernel to use PCI Conf1 access instead of
MCFG-based access.

Why did the ordering of my NIC devices change in Red Hat Enterprise Linux 4.5?
The 2.6.9-55 version of the Red Hat Enterprise Linux 4 kernel (Update 5)
reverts to the 2.4 ordering of network interface cards (NICs) on certain
systems. Note that if the "HWADDR=MAC ADDRESS" line is present in the
/etc/sysconfig/network-scripts/ifcfg-ethX files, the NIC ordering will not change.
To restore the original 2.6 ordering, which is different from the 2.4 ordering,
boot with the option pci=nobfsort

Remember that this is just that it will install paravirtualized, not that it
will be a host.

Thanks Stephan,
I was going to ask you if you had any updates. It looks like it's compiling
clean with all my scripts. It should be in the next beta.
