Hello, Andres! > Just out of curiosity, what happens if you enable devfs (devfs=mount; > don't forget to install devfsd, also) and try the same thing? I'm getting the same behavior with both devfs and static dev. Output is as follows: DevFS: ====== [Plug-in FireWire CDROM Drive] Dec 27 17:22:58 tucker kernel: ieee1394: Error parsing configrom for node 0-01:1023 Dec 27 17:22:58 tucker kernel: ieee1394: The root node is not cycle master capable; selecting a new root node and resetting...
