  IBM ThinkPad 600X
  Xircom "CreditCard Ethernet 10/100-Ready" pcmcia card

without fail.  The only way to unlock the system seems to be by sending it
an interrupt (like inserting another pcmcia card).  If I continue with the
ftp (or copy) it will lock up again (only this time I am out of pcmcia

Is this reproducible on any other computers you have?   I believe this is a
hardware issue.

This works flawlessly on all of the systems I have tried.
