Actually, I rather doubt that it is, all systems can use 127.0.0.1 as a loopback address, but all sure don't have an extra interface show up. I don't know what it is though. You might want to watch closely during the boot process or even boot in expert mode and watch each step. 3.8.1 has been detecting firewire interfaces that are not really there, which may have something to do with it, or you might even really have a firewaire interface in that computer (firewire tends to show up as a network interface).
