Hidetoshi:
Here are some patches I came up with that update sbp_targ to work with
FreeBSD 6. I added a new XPORT type for FireWire, added a no op for
XPT_SET_TRAN_SETTINGS and coded(stolen from sbp.c) to do "stuff". I've
added a couple of printf's for my own logging, but they are useful for
others.
I wrote a small shell script that I'm using with my testing(see attached
start_firewire.sh).
I've attached my kernel configuration for your review(see attached file
BRUNO).
I've also noted a witness error in sbp_targ that looks like a Giant failure:
