My previous problem report was based on 6-stable.
I tried with 7-current, but the bge device didn't even work...

With cable plugged in, "ifconfig bge0" doesn't 
recognize the online status:

bge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
        ether 00:17:a4:8f:22:bc
        media: Ethernet autoselect
        status: no carrier

And when running ifconfig to set V4 address, FreeBSD itself gets frozen.
7-current% ifconfig bge0 inet 192.168.0.100 netmask 0xffffff00
(... frozen without any message... I need to reset the server hardware.)

So, only information I can take is the below sysctl message,
but without any packet send/receive.
