This is Linux not NT things dont stop working for no reason. What did you do to the sytem before it went down. Any strange messages in /var/log/messages? Is your ethernet card still detected?
You say that you applied the patches both times. Maybee the new netconfig has some bug in it. Try to bring the interface up by hand with
ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up (replace the ip and the netmask to the appropirate value)
route add -net 192.168.0.0 netmask 255.255.2 eth0 (again replace ip and netmask with appropriate values)
Try to ping another machine. If it works netconfig is the problem if not I am guessing the ethernet card (weel i was gonna say its dead but you said you ruled the possibility out) has some irq conflicts try procinfo -a you see the irq used by the ethernet card? Is it being used by some other device? If it is try changing the irq that the ethernet card is using.
I understand this is kinda of vauge but please post more info on the problem and there is a better chance somebody is gonna understand what the problem might be.
