These messages might be harmless (at least, I'm also seeing them and
firewire works mostly fine here).

Check if the sbp2 module is loaded:
$ lsmod | grep sbp2

If not, load it manually (keep an eye on /var/log/messages):
$ sudo modprobe sbp2

The recent kernels are very picky about module options, so if you have
any set in /etc/modprobe.conf ("serialize_io=1" is very common), make
sure they're spelled out correctly and without any trailing spaces.

Also, you might try experimenting with when the disk is turned on (prior
to or after the system is brought up).

Hope that helps,
