The firewire stuff apparently doesn't work too well on linux-2.4.18
I have 3 SCSI disks plus a SCSI CD-R/W. The Adaptec Firewire controller
has a 80 gig disk plus another CD-R/W attached. Both of these run fine
(but slow) in W$.


When I `insmod sbp2.o`, I get a signon message showing two CD-R/W drives,
and no Disk. I can't find any 'devices' to access or mount. I thought,
maybe, that the CD-R/W should show up as the next SCSI CD-R/W, i.e.,
/dev/scd1. If I do `od -x /dev/sdc1` (to see if its readable), the
machine panics. The panic isn't anything that can be copied as it scrolls
for about 10 seconds and end up with:

	code : : : : : : : : :

	(not too useful).  Nothing gets written to the root file-system,
not even the signon-message when I inserted the module.


Cheers,
Dick Johnson
