I'm using syslog-ng and all infos are going in /var/log/kernel. At 
http://linux.dej.ro/3c59x/kernel.txt I posted the part wich is interesting 
for us (between Dec 12 17:29:24 and Dec 12 17:43:29(when the machine it was 
rebooted)).

If you remember that problems apeer on my machine when I'm used the 
eepro100 driver (Net Drivers!?! thread on linux-net).

It's not so much :) It was up for 3 days.

I don't understand this. Be more explicit and tell me what to do when the 
card hangs again.

Why the card loosing the interrupt? Is this a kernel bug, a driver bug or 
a mainboard bug?

I have to wait for the next time ... but I'm very patient :))

This option will afect my SMP box?

Newer kernel? My kernel is 2.4.20 the latest and I can't use 2.5.
At http://linux.dej.ro/3c59x/ I posted the patch over 2.4.20 vanilla wich 
I applied and it runs on my machine.


Thank you,
