How to do Firewire in 4.8

[Paul Hoffman]

Just a clue for those folks who saw the 4.8 announcement say 
"Firewire support" but wanted to know how to get it to happen. You 
need to recompile the kernel with the following two lines in your 
configuration:

device          firewire        # Firewire bus code
device          sbp             # SCSI over Firewire (Requires scbus and da)

(Found this in the LINT file, but not in GENERIC).

I compiled this, tossed in a generic Firewire card, and it worked 
first time, adding the attached hard drive as device da0.
