I posted something about this back on April 25,
Message-ID: <6bb609560704250801y6efe4ec1gbc513ea4f34d5721 at mail.gmail.com>

What I said then was:

--------
The problem (as I recall) is that on each reboot the onboard NICs are
being discovered in a different order, so the MAC addresses in
/etc/sysconfig/hwconf don't match what is recorded in
/etc/sysconfig/network-scripts/ifcfg-eth*.

I believe what I had to do (I should have written it down, damn it)
was hand-edit /etc/sysconfig/hwconf to completely remove all the
references to the NICs (there may be more than one entry for each NIC
because of the flip-flopping), edit ifcfg-eth* to remove all
references to HWADDR, reboot again to let the cards be rediscovered,
and then again hand-edit ifcfg-eth* to insert HWADDR lines that match
the device assignments in the regenerated /etc/sysconfig/hwconf.

However, I may have at least the last step of that wrong.
--------

No one ever responded as to whether that solution worked for them.
