/etc/rc.d/netif & em interfaces

I'm having an interesting problem on a fresh 8.1-RELEASE1 install.
I'll start by saying this didn't happen on 7.1 on the same exact
machine.  I've been fighting with this for 2 days now and have come up
with no answers on my own, so I'm hoping one of you guys can have some
insight here.

When I run "/etc/rc.d/netif restart" (also happens with a stop /
start) , I can no longer get to the server over the network.  When I
do a packet capture on my workstation, it looks like it's MAC address
changed somehow.  The first two bytes of the address are different.
For example, the real MAC is 00:15:17:1b:cf:7a , but I'll see the
replies from a MAC of  "02:67:17:1b:cf:7a".  After each run of
"/etc/rc.d/netif restart", the first two bytes will change again.  I
have to reboot the server to get it working again.  The "em" cards in
question are:

dev.em.0.%desc: Intel(R) PRO/1000 Network Connection 7.0.5
dev.em.0.%pnpinfo: vendor=0x8086 device=0x108c subvendor=0x8086
subdevice=0x348d class=0x020000
dev.em.1.%desc: Intel(R) PRO/1000 Legacy Network Connection 1.0.1
dev.em.1.%pnpinfo: vendor=0x8086 device=0x1076 subvendor=0x8086
subdevice=0x348d class=0x020000

FWIW, this is on an Intel 1530 series server.

Thanks in advance,

Brian McCann
