Redhat AS4 (Release 3) on Dell Poweredge 1950

[Dirk Allaert]

Maybe Dell can fix this issue, this may save us all even more time. The 
network cards are not just switched. Look eg at /etc/sysconfig/hwconf 
and compare that with ifconfig output, take a close look at the mac 
adresses, kudzu reports them reverse from ifconfig!

This is a really annoying problem, because we are running Xen and this
causes even more problems and confusion. After starting Xend,
networking does not work anymore. But if we manually reassign the
adapters like this:
brctl delif xenbr0 vif0.0
brctl delif xenbr1 vif0.1
brctl addif xenbr0 vif0.1
brctl addif xenbr1 vif0.0
networking works again. It is like eth0 and eth1 are assigned reverse,
while vif0.0 and vif0.1 are assigned the way you would expect.
