[wellylug] mounting a firewire ext HD

[Pete Black]

You need to modprobe sbp2 (serial block protocol?) at the very least, 
and if you are running a 2.6 kernel don't expect firewire to work 
solidly. There are a number of serious regressions from 2.4->2.6 
w/regard to firewire (lack of Multi-LUN support so no multi-drive 
enclosures and others). 2.6.11 and they still aren't fixed, though I 
believe there is some progress in the ieee1394 cvs drivers.

I have found I often need to completely rmmod all the firewire related 
modules to get my machine to recognise my iPod - and it is quite 
possible rmmod will hang while doing this - requiring you to reboot to 
restore firewire operation.

Also ensure you pass the serialize_io=1 argument to sbp2 unless you want 
to see your transfers go at a snails pace with frequent timeouts. check 
dmesg to see if the serialize_io arg is accepted.

Once you get it working it seems to function OK - However 2.6's firewire 
support is not in a particularly good state - bad defaults, missing 
functionality, misbehaving drivers and incompatibility with lots of 
hardware.

Let me know if you can't get it going and i will see if i can suggest 
some more things to try.
