Question Firewire disc adds multiple devices to kernel 2.6 (sda, sdb, .. , sdh)


The only thing that held me back from upgrading permanently to kernel 2.6 is the way my external firewire disc and my ipod behave. They both work perfectly under 2.4. The first that gets plugged in is /dev/sda and the second /dev/sdb.
With 2.6.8, when I turn the disc on, I get 8 devices (sda to sdh) and when I plug in the ipod I get 8 more (starting from sdi).
I can mount both discs, though.

Is this strange or is this normal?

Thats the dmesg part after plugging the first disc in:

Unhappy definitely NOT normal

Well, something is definitely not normal, because the ieee1394 / sbp2 system crashes with kernel 2.6.8 when I have a lot of processes doing something with the disc (i.e. having many copy dialogs by draging around some folders to or off the disc).
I wonder if this could have something to do with the udev thing, which I dont really understand.
Maybe I have a mix of udev and the old kernel 2.4-like device system?

Anyone knows more?

THanks

Thumbs up newer kernel

with the 2.6.11.7 kernel it works allright, except for
Code:
ieee1394: Error parsing configrom for node 0-01:1023
ieee1394: The root node is not cycle master capable; selecting a new root node and resetting...
ieee1394: Error parsing configrom for node 0-00:1023
ieee1394: Node changed: 0-00:1023 -> 0-01:1023
ieee1394: Node added: ID:BUS[0-00:1023]  GUID[0050770e00071002]
ieee1394: unsolicited response packet received - no tlabel match
The strange behavior with the multiple devices must have had something to do with a buggy firewire kernel module in 2.6.8.
