This is here:

        /*
         * an EOF condition results in a VALID resid..
         */
        if(xs->flags & SCSI_EOF) {
           ^^^^^^^^^
                xs->resid = xs->datalen;
                xs->flags |= SCSI_RESID_VALID;
        }

Looks weird.  sc_err1() does always evaluate xs->error first, so this
should already break if xs is an invalid pointer.

Never trust an operating system you don't have sources for. ;-)
