I tried another FreeBSD-stable box and an IEEE1394 CD-RW drive to get
the same unstable results. Both boxes include ASUS TUSL2-C motherboard
and VIA VT6306 FireWire card (http://www.winbest.com.tw/5010.htm).

I also tried Texas Instruments TSB12LV26 card with this box and the
result was quite satisfactory.

So, the problem seems to do with VIA VT6306 FireWire controller. How
do you think of this idea?
