I took the card out of my firewall and put it into my test box.  The
test procedure was to ping a third machine from the text box and then
start pinging the test box from the second machine using large packets.
The rev K card would always stop receiving permanently until a
ifdown/ifup was done.

I tried three other cards and they only showed heavy packet loss from
the ping running on the test box.  The packet loss went away when the
second machine stopped pinging it with the large packets.

Here's the list of cards:
