Can you get the panic message?   This seems really odd as rman_init() will
only panic if rm_type is set to an invalid setting, but it should always be
correct in this case:

        w->rman.rm_type = RMAN_ARRAY;
        snprintf(buf, sizeof(buf), "%s %s window",
            device_get_nameunit(sc->dev), w->name);
        w->rman.rm_descr = strdup(buf, M_DEVBUF);
        error = rman_init(&w->rman);
