I've seen this sort of thing on other architectures.  Other operating
systems, too (AIX).

When I've seen it, the cause has been a bad autonegotiation, where
one half of the link thinks the line is full duplex, and the other
half of the link doesn't support it.  Everything starts out ok, but
then TCP acknowledgements get lost because they're transmitted at
the same time as another packet in the other direction, and then
everything slows down to a trickle.

What is on the other end of your network line?
