freebsd stable - Mar 2008 - 7-STABLE not seeing second em interface on supermicro mb

I just installed 7-STABLE on a new dual/quad machine based on a 
supermicro motherboard - it works fine except that it's not seeing the 
second network interface (em driver) - is there a magic incantation to 
make this work?


FreeBSD echelon.localnet 7.0-STABLE FreeBSD 7.0-STABLE #0: Fri Mar 21 
23:27:31 PDT 2008     
root@echelon.localnet:/usr/src/sys/amd64/compile/ECHELON  amd64

The only word from the em driver is this

em0: <Intel(R) PRO/1000 Network Connection Version - 6.7.3> port 
0x3000-0x301f mem 0xde200000-0xde21ffff irq 17 at device 0.0 on pci5
em0: Using MSI interrupt
em0: Ethernet address: 00:30:48:64:d9:45
em0: [FILTER]

ifconfig doesn't show anything other than em0 and lo0

Where should I start debugging this ?

What Supermicro system or motherboard is this?  I have many, so I can
confirm/deny what you're seeing on other systems.

Start with:

1) the BIOS -- you can enable/disable NICs there.  If both show enabled,
try Load Setup Defaults to make sure there's no CMOS corruption
(sometimes this happens when upgrading BIOSes, and may have happened at
the factory -- who knows).

2) Jumpers on the motherboard -- many Supermicro boards have actual
jumpers on the board to disable either NICs, in addition to the BIOS
option.  Check these.

Can you give us the output from "dmesg" after a verbose boot, and also
the output of "pciconf -l"?  Are the network interfaces on board, or
on a
separate card?

John,

I'm not aware whether or not your question has been answered. If not,
please send output of `pciconf -lv'.
