Running the following:

FreeBSD 4.4-STABLE #2: Wed Sep 19 15:49:21 PDT 2001
...
dc0: <Davicom DM9102 10/100BaseTX> port 0xde00-0xde7f mem 0xefffaf80-0xefffafff irq 10 at device 11.0 on pci0
dc0: Ethernet address: 00:d0:09:3a:a3:bf
miibus0: <MII bus> on dc0
amphy0: <Am79C873 10/100 media interface> on miibus0
amphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
...

Packets coming in often get lost or are received with very high
latency, often multiple times for a single packet.  There are dc0
interrupt timeout errors an in the log as well as a couple others i
can't remember at the moment.

It is part of a noname made in china cheap celeron motherboard.  Any ideas
on how to fix this?  (it works without problems under linux but i have
enough linux boxes around already)
