46 In fact, you may have a firewire connection, and that is being
47 recognized as eth0, try adding "nofirewire" to your kernel boot line,
48 and check if eth0 will be your network card again. Also, there was a
49 similar problem on the list a few days ago and the OP of that thread
50 asked for UDEV rules to set names to its interfaces, check the
51 archives.
