Strange things happen,
once I got three pings through, 5 secs, 4 secs and 3 secs respectivly,
then the machine locked.

Once I even could initiate a telnet session, but I couldn't reproduce
it.

Some more details, maybe they're helpful...
Whenever I insert the pcmcia ethernet card, I'll get an arp entry for
the laptop that looks like

Address HW type HW address Flags Mask
192.168.1.20 UNSPEC 00:00:00:00:00:00 MP *

Removing or overwriting it with correct data is not possible.

FWIW, here's a tcpdump of the problems wit a 3c589 pcmcia
ethernet card and 2.1.26

Winpc is a desktop machine, 192.168.1.20 ist the laptop. They are in the
same Class-C

-- 12:53:59.327144 arp who-has winpc.rfc tell 192.168.1.20
This request already takes around 2-5 secs to show up after starting
telnet (with an ip address, no dns timeout here...)

-- 12:53:59.327144 arp reply winpc.rfc is-at 0:80:c6:3:34:30

That moment the laptop locks.
