It's not that the device isn't detected, it's that the system is
renaming it. Often different kernels will scan the PCI bus differently
and the names will change. I hit this with two kernels with minor rev
changes on a single Dell 2850. Even the same kernel run on two slightly
different hardware platforms will cause issues. A Dell 2850 scans the
motherboard first, then the PCI bus. A Dell 1850 will scan the PCI bus
first, THEN the motherboard. Sheesh! Consistency, please!
The most reliable method to tie an interface name to a specific NIC is
to either create an /etc/mactab file with the entries in it, e.g.:
eth0 aa:bb:cc:dd:ee:ff
eth1 gg:hh:ii:jj:kk:ll
or add the "MACADDR=aa:bb:cc:dd:ee:ff" line to the ifcfg-ethX file
involved. Of the two, I prefer the second one ("MACADDR="). One less
thing to look at (if you have a problem with NIC naming, check the
network config files instead of something in /etc). But then, I'm a
lazy cuss! :-)
