Great!
Can you put up a verbose /var/run/dmesg.boot again?

You could try adding "options TWA_DEBUG=x" with x being a number from 0
to 10 (no debug output up to very verbose I assume), and see if that
shows us more.
I have one issue left in the port, and that is determining what to do
with the lockfunc and lockfuncarg that FreeBSD passes to
bus_dma_tag_create() (see "XXX swildner" comments in
sys/dev/raid/twa/tw_osl_freebsd.c). I will look at this.
Please keep us informed on anything you discover.
