Nothing in here is jumping out at me as being wrong, sssuming that
ccb->ccb_h.status isn't being changed before you return.  Try
emailing Ken Merry (ken@freebsd.org) directly to see what he thinks.

I'm impressed that Agilent is doing a FreeBSD driver for the Tachyon.
Will it be fully open source or half open/half closed?  Also, will it
do fabrics or just AL?
