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.
