D-Link and Linux(Mandrake9.1)

After much searching and quite a bit of frustration(read hair ripped out by the root). I have decided to come here.
For about two weeks now I have been running linux as my server. One of my NIC cards has a F%*KING problem with staying up. It seems that after about 8 hours of inactivity I have to reboot my server to get my network card to respond again. Its the DFE-550TX. It acts like that card goes to sleep, but its more like it dies completely. Nothing seems to wake it(much like that Uncle that comes over around Thanksgiving, and falls asleep on the couch and no matter what you try he stays asleep). Its about to turn me back to M$. Winduhs has its problems, but at least I only had to reboot it once a week.

You should include some things like what you have already tried that didnt work.

output from command: ifconfig ethX
while the device is asleep

and possibly check your log files for problems.

from ifconfig eth1

Which log should I look in?

for most distros you would look in /var/log/messages but there may be some other interesting stuff in /var/log so check it out.

I have some other questions:

1 What distro do you use?
2 when the nic is failing what is returned by the ping command? ping the device and loopback then maybe your gateway if the other 2 respond.
3 Any other nics in the system?
4 Was that output from while it was failing?

1) Mandrake Linux v 9.1
2) from the server

On the machine attempting to connect
"Request timed out"
Um loopback(127.0.0.1)? gateway?
3)yes
eth0 - internet connection
eth1 - failing one
eth2 - second machine connected. No problems with it.
lspci -v

any other logs that might help?

finally a failure noticed in messages

dhcpd: receive_packet failed on eth1: Network is down

martian source 192.168.1.255 from 192.168.1.4, on dev eth1

I havent been able to find a definate answer on this but from I gather, this error you are recieving is saying that the kernel is dropping the packet because it beleives that the source is invalid.

This command may possibly help:

echo 0 > /proc/sys/net/ipv4/rp_filter
