Network connection dies after a few minutes

[stp_1993]

I just got back home and am trying to use my gentoo box.
Unfortunately, there was a power failure during the summer, and the filesystems got unmounted cleanly.

Now, whenever I use the network for a few minutes, the connection dies. I can't even ping local machines on my network.
How can I troubleshoot it? Is there a network ebuild that I can re-emerge in case some file was corrupted?
The network works fine from my windows machine.

Do your log files say anything after the connection gets lost? dmesg? Which kernel? Which network card?

Hello 911? How are you?

post some infos like

> lspci | grep Eth
> ifconfig -a
> rc-status | grep eth

perhaps this could help to show the current status

Ugh. My system is really screwed.
If I try to '/etc/init.d/net.eth0' it hangs on "Unmounting network filesystems".
If I try to reboot, it hangs.
If I try to do 'sync ; sync' it hangs.

This is only after the network stops. If I reboot before the network gets a chance to die, it reboots fine.

Here's my dmesg output:
If you need answers to the other questions let me know. It's just a big pain for me to copy text from the machine, so I don't want to do it gratuitously.

Has anyone found a fix for this? It used to hang once or twice a month, but it's now hanging once or twice a day after switching from an amd64 3000 to an opteron 165. Noapic and nolapic seems to help. I tried noacpi, but it caused sata controller to hang...
