AFAIKS both ends configure as half-duplex as they should. Also tried a
more high-end switch to rule out buffering problems between 100baseT
and 10baseT ports. What stuns me is that these network cards work just
fine in my thinkpad (attached to the same switch). Also, NetBSD-1.4.2
works just fine.

The link light goes out after receipt of a burst (of about 17Kbs) of
packets (it's not an activity light). Each time a few secs before the link
goes down, filesystem activity stops (I ran a `ls -R /` in the
background while trying to do an ftp to test this) and continues after
the link light blinked.

I'm clueless. Any ideas?
