ieee1394 / sbp2 problem accessing iBook in target disk mode

[rene.rebe]

Hi,

I tried to access another iBook in target disk mode via the sbp2 driver 
running a 2.4.22-benh2 kernel. The device (the other iBook) is detected but 
can not ba accessed properly:

Of course it works under MacOS-X and also networking via the eth1394 driver is 
working nicely between the two Linux iBooks.

Is this problem know or any ideas?

Using a LaCie Firewire disk the sbp2 code works perfectly:
