There are 2 possible Kernel modules for the 3-Com 905 cards. We have 
had a machine even crashing with kernel panic using the (normally 
better) 3c905 module. So we changed to the other module. We used RH 7.0 
running Kernel 2.2.16. The machine has three NIC and traceroutes (ICMP 
packets) from machines inside the DMZ to remote hosts crashed the FW-1 
while the 3c905 module was used.

from /etc/modules.conf of that particular machine

# better use the old module for the 3-Com Cards

Might also have something to do with the fact, that the stateful 
inspection needs computing power.

Besides that I'd like to know whether others have faced similar 
problems using 3-COM 905 Cards with RH 7.0/FW-1
