I have a solution that is rather unconventional, but it works - every 
time, without fail.

Step 1: yum install wireless-tools

Step 2: Create a file with vi (or similar) called /etc/iftab... Sample 
below:

The file contains a mapping from mac addresses to logical names... Eg:

       eth0      mac 08:00:09:DE:82:00
       eth1      mac 08:00:09:DE:82:01
       eth2      mac 08:00:09:DE:82:02

Step 3: Execute /sbin/ifrename in an appropriate init script. (Just 
after the normal network startup stuff would be a good place).

What does it do? If Linux gets the names of the interfaces "wrong" 
during bootup, it will rename them to the correct names. It was designed 
for wireless cards, but it works really well in all of my tests for 
multi interface systems.

I hope this helps anyone with this issue.

Regards,
Greg.
