Hello,
To bring a little bit of closure to this issue, I'd thought I'd share my
workaround since it doesn't seem the driver will be fixed anytime soon (if
it is a driver issue?).
Basically,
1) Recompile the kernel WITHOUT the "device em" line. Make sure the if_em
module compiles though (which will be done unless you've specified
MODULE_OVERRIDE somewhere).
2) Edit /etc/rc.conf (or /etc/rc.conf.local or otherwise) to include:
network_interfaces="lo0 em0 em1" (Plus any other interfaces you may have)
This effectively moves the driver loading to when the ifconfig em0 statemnet
is called, which is when the IP is added. Setup properly, IPMI will
function through single user mode, FSCK, etc and the complete boot sequence.
Tested with 6.1-PRERELEASE. I'm not sure of how ifconfig or the netif
startup script acts in other versions. Worst case - if the device driver
isn't loaded, then IPMI should still work ;)
- Matt

Subject: RE: IPMI During Boot
Hello,
The help is much appreciate. Just to test thoroughly, I recompiled my
kernel without the em driver, and I didn't load the module in loader.conf.
Upon rebooting, it flew through just fine, and I was even able to drop to
single-user mode with no issues. I then enabled the em module in the
loader.conf, and got the results as before, I'm dead in the water until the
network is configured.
Below is the information you requested.
The IPMI Card is currently configured as:
IP: 192.168.2.110
MAC: 00:30:48:2F:A0:80
Here's the ifconfig:
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=b<RXCSUM,TXCSUM,VLAN_MTU>
inet 192.168.2.105 netmask 0xffffff00 broadcast 192.168.2.255
ether 00:30:48:2f:a0:80
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active

Hmm, well I've been told that using the same IP address or not should
both work :)
Matt, can you do a pciconf listing for me, I'd like to see exactly what
MAC you have. The most recent systems that are AMT capable
need some special code in the driver that FreeBSD doesnt yet have.
I'm wondering if that might be whats happening here.
Jack
