Hmmm... what's the output of 'ifconfig fxp0'? Are you by any chance
running this card in half-duplex mode?
If you were connecting to a hub (rather than a switch) and all of your
network was running half-duplex, then that level of collisions wouldn't
be particularly remarkable. However nowadays basic 100Mb switches are
cheap, so that would be rather unusual. However, a card that fails to
autonegotiate with the switch will fall back to running at 100-half.
That's generally pretty obvious because performance will be abysmal.
Other alternatives are hardware problems -- try a different ethernet
cable. Try plugging into a different port on the switch. Try a different
computer on the cable etc. where you're seeing the problems. If none of
that identifies a fault in the cabling, then it's looking more likely that
your network interface has gone fubar.
Cheers,
Matthew
