    The following code is used to set the channel to listen to for
    iso receive.

    int raw1394_set_channel(struct raw1394_handle *handle, int channel)
    {
        struct fw_isochreq chreq;

        chreq.ch = channel;
        chreq.tag = 0;
        if (ioctl(handle->fd, FW_SRSTREAM, &chreq) < 0) return (-1);

        return 0;
    }

    This code crashes the system.  What are we doing wrong here?

    It used to work OK last june 2003 in version 1.2.4.10 of fwdev.c

    Also, how does one stop iso listening on a channel?
