Help: malfunctioning forcedeth driver

Ladies & Gents,

It seams that some time in the last few months the forcedeth driver has begun to malfunction in my lappy. The last time I used a wired connection was a few months ago when I was having trouble with my wireless access point. Last night I hooked up to test the dhcp server on a new firewall I am building only to discover that my lappy was foo-boo-d. I have notice over the last few months that there have been some connectivity issues with my wireless, sometimes forcing a reboot to be able to reestablish a connection but I am not sure that it is related.

Code:

$ uname -r
2.6.26-1-amd64

$ dmesg | grep forcedeth

$ sudo ifup eth0

Ignoring unknown interface eth0=eth0.

$ sudo ifup eth1
ifup: interface eth1 already configured
$

I do see what looks like a ipv6 mac on eth0 but the mac for eth1 is what is listed for forcedeth. This leads me to think that ipv6 is involved somehow.

This machine does get hibernated a lot but a reboot did not fix the problem. Tried that first.

It is also puzzling that ifconfig reports the existence of an interface that ifup can't find.

I have been looking on google but everything I have looked at so far is dated and not seemingly related to my problem. The lan worked out of the box.

Any thoughts? Thanks.

OK I found the problem. It seams that the nic has gone bad. I tried the 2.6.25 kernel and it dido't work there either so I though I haven't booted vista in a long time, so I did and the nic does not work there either. I even updated vista while I was there, reminded me about why I don't use windows anymore, what a pita updating it is.

It seams that when I updated vista it changed something in relationship to the touchpad and now the buttons are reversed. I have tried changing the mouse buttons in the kde control pannel like I did before to switch them the first time but that didn't work.

Thanks again even though you were not able to help this time.

Ok a reboot with the mouse switched back to right handed and then changing it back to left handed in in the kde control pannel fixed it.
