Description of problem:
Only device that had been connected to FireWire was iPod, and it has
been unmounted AND ejected for hours (ejected as in /dev nodes been
removed, no "do not disconnect" message.
I needed to do something in windows, so I rebooted from gnome.
I think I physically disconnected iPod before choosing reboot, but it
is possible I chose reboot and then physically disconnected.
Here's the panic that resulted:
ieee 1394: sbp2: aborting sbp2 command
Test Unit Ready 00 00 00 00 00
Kernel panic - not syncing : drivers/ieee1394/sb2.c:505:

is only there for times when I need to connect a second 6-pin firewire
