I've seen these sort of symptoms before and it turned out
to be faulty memory.=20

Back in 2.2 I had a box which picked the behavior up if
you did a ifconfig down/ifconfig up after it had been running
for some time.

tcpdump on the localbox it that case showed Ok (outgoing) packets, but=20
another box on the same network segment showed the same packets as
corrupted.

Changing the RAM cured it completely.
