Ethernet port doesn't detect the cable is connected and doesn't function

It's since this morning that I can't make my en0 ethernet port work. Please note: changed dozens of cables, hubs, etc. The port simply doesn't detect the cable is plugged in and the actual network interface configuration crashes with the following log upon system boot-up:

MacBook, Mac OS X (10.5)

I had a similar issue with a MacBook Pro. When connecting the network cable, the network preferences would show 'not connected'. I thought it was hardware, but when I transferred the user to another Mac, I found that that ethernet device all the sudden stopped working as well.

I was able to get the ethernet back with:

System Preferences
->Network
->Assist Me...
->Diagnostics...

At some point the ethernet device went green and all was well.

Maybe this will help.
