Ok, I did some extensive tests overnight.
Essentially I still had `fwcontorl -g 20` and
SBP_QUEUE_LEN=1 and maxopenings=1 and `debug.sbp_debug=1`.
hw.firewire.sbp.max_speed started at 0 and got 2 at the end.
After treating two `iozone -s 51200m -r1024k` on the platters
overnight without problems I started with a plain sbp.c and
no `fwcontorl -g 20`. I get constant rates of 13MB/s on each disk.
No problems so far.
Seems you got it. Thanks!

BTW: switching on debug.firewire_debug gives zillions of 'kick'...
Is this just a notification about the code-path?

Bye!
