Perharps, it is the same problem I got with a dc card one week ago, and
which seemingly did not interested anyone.

Using black magic, I solved it by putting:

hw.cbb.start_32_io="0x4000"

in my loader.conf...

I found it by googling, and trying a trick used for a different card, in
a different computer, with a different version of FreeBSD !
I do not know why it works, but it works...

Is there somewhere a tool or a set of procedures to diagnostic/solve
this kind of port allocation problems, which manifest itself with
different kind of messages (as I found when trying the same card on
another computer) ??
