Restarting from other OS into Kubuntu causes eth0 to not be recognized.

[dwightpaige79]

I have an annoying problem on a multiboot box with Kubuntu, Sabayon, and Mandriva. If I boot out of either Sabayon or Mandriva and into Kubuntu I have no internet. I can't get internet with 'ifconfig eth0', 'ifup eth0' or '/etc/init.d/networking restart'. This is because something is causing Kubuntu to not recognize eth0. If I turn off computer AND turn off it's power supply for 15 seconds or so and then boot directly into Kubuntu internet works fine. It is only when booting out of other OS's and into Kubuntu that I lose internet. What could possibly cause this?

I have wicd installed after first doing 'aptitude purge network-manager plasma-widget-network-manager'. To my knowledge no other network managers are installed. The following data is gathered from Kubuntu with internet working:

$ cat /etc/network/interfaces
auto lo
iface lo inet loopback

$ sudo ethtool eth0

In the situation where I don't have internet the result of 'sudo ethtool eth0' has this difference:

Link detected: no

Any one have any ideas? Obviously let me know if any other info needed. Should mention I have Guarddog but didn't perceive this as a firewall issue as when I boot into Kubuntu directly from computer off/power supply off I do have internet no problem.

I am going to reboot into Kubuntu with out internet and gather some more info including results of 'ifconfig eth0'. Would there be any advantage to doing a manual net config? Following Detonate's post?:

Is there possibly something in grub causing this. I'm using Kubuntu's Grub installed on MBR.
