Ports card and Win/TCP won't play nice

[Colonel Panic]

I'm having a somewhat bizarre problem changing to a newer-generation
ports card on an existing 386 UNIX box.

The players:     AT&T 6386E/33 (33 MHz 386, Intel-made) w/24MB
                 AT&T UNIX System V/386 Rel 3.2.2
                 WIN/TCP for 386 STREAMS Release 3.1.0
                 WD8003E Ethernet Card
                 Consensys PowerPorts 16/512  16-port card
                     (to be replaced by:
                         Consensys PowerPorts/HD 32-port card)

The problem: the existing setup is working dandy.  I went to replace
the existing 16-port card with the new HD card.  Once the hardware and
software are installed and I reboot, I get lots of messages out of
the network driver (specifically, the n8390_recv() function).  The
network software, however, appears to still work to some degree (I can 
rlogin to the machine with one session just fine).

The ports card and network card have nonconflicting i/o base addresses,
and nonconflicting shared memory addresses (the ports card uses
CE000-CFFFF; the network card uses D0000-D1FFF).  I have tried moving
the shared memory addresses of both with no impact.  The ports card
uses defaults for everything, while the network card uses i/o base
240H and IRQ2.  The network card is in slot #1, and the ports card is 
in slot #4, if that means anything.

When I gave up and reinstalled the old ports card, things are hunky
dory again.

Any ideas appreciated.
