Intel PRO/100+ : "Receiver lock-up bug exists"

[Pascal Voisin]

Hello !
I have two INTEL PRO/100+ cards running on a Mandrake 6.1 Linux machine
(Linux version 2.2.13-22mdk). The cards are working but I get the
following message in my dmesg output. What does this "Receiver lock-up
bug" mean. Also I am trying to  connect to this machine with a laptop
equipped with a Xircom PCMCIA Realport 10/100. I cannot get connected at
more than 10mbs. I get always the message "eth0: auto negociation
failed; using 10 mbs". Could it be related to the problem on the Intel
card ? How can I be sure that my server can run at 100mbs and that
auto-negociating is working  ?
Many thanks for your help
Jacques
