Hello

I guess my problem is related with this
http://www.scyld.com/pipermail/vortex/2002-November/002013.html. This is my
story of it.
I have my roter/firewall, it has eth0 and that is a 3c509b and a eth1 as
internal interface and that is a 3c905C-TX-M. It has worked fine for a long
time with kernel 2.4.19 and then 2.4.20pre7 and for the last weeks,
2.4.20pre11. It have been connected to a old 10mbit hub. Today I invested in
a new "FSW-2108TX" switch from "level one". I connected the network cable to
the switch and click, the 100mbit and full duplex LEDs lights up on the
switch. I'm very happy for my new switch :) After a few hours I noticed my
internet connection stopped working and I found the link LEDs on the switch
black :( I tried to revive the link with "ifconfig down" and start it again
but now it is dead. I rebooted and the LED is still black. I turned the
computer off for a few seconds and then back on, now the link LED is on
again and everything worked normal... a few hours later... no internet again
:( This time i saved the syslog (links at the end) from the death of my eth1
link and my attempts to revive the connection. The problem must have some
connections with the 100mbit or full duplex settings I guess. BTW the switch
also has auto-negotiation.

First death of eth1: http://217.210.183.83/eth1_dies.log
Second death of eth1: http://217.210.183.83/eth1_dies_again.log

I hardly believe that this is enough info for you to fix the problem but if
you tell me what to do, I will follow your instructions. As a temporary
solution I put the 10mbit hub between my eth1 and my new switch.
