 em0 at pci0:12:0:  class=0x020000 card=0x002e8086 chip=0x100e8086 rev=0x02 hdr=0x00
 Cable was disconnected...

  It seems so, because the first message in `dmesg' is BEFORE

ipfw2 initialized, divert loadable, rule-based forwarding disabled, default to deny, logging disabled

  and RIGHT AFTER "Trying to mount root from ufs:/dev/ad0s1a".

 BTW, card WORKS in such conditions: I can connect cable, and ping
this interface (this is head-less computer, I access it through wi-fi
from my notebook while wired network is stopped).
