I recently moved this machine to a different network replacing an old computer. Without obvious cause I lose connectivity to this server. I initially thought that there was another device trying to advertise the same IP address (odd because I swapped IPs when I swapped machines) so I changed the IP addresss to something that I knew wasn't in use and cleared arp on my router. Same behavior, so I figured bad network cable/hub port so I replaced, same behavior. I now have a serial console cable on this machine, after I lost connectivity again tonight I connected on the console. ifconfig -a shows the interface up, the machine hasn't rebooted. The only thing that I can see that is odd was an arp -a didn't show neighbor computers nor the local interface ([permanent]) entry. I'm kind of at a loss as to what to try next. This machine worked fine on my home LAN. Below is the dmesg, I'm using the fxp interface, I added the ed today out of despiration. Any help would be greatly appreciated.
