Is this a hangup, or is it a delay of about 50 seconds on access to the
first file after the reboot?  We see such a delay (when booting from
Solaris) on every BSP except the mv167 - I can't explain why that BSP
isn't affected.  There is a way to get around it by adding the following
code to your <tornado>/target/config/all/usrConfig.c file:

    {
        int mybsock;
        struct sockaddr_in mybsockaddr;

        mybsockaddr.sin_addr.s_addr = htonl(INADDR_ANY);
        mybsockaddr.sin_port = 0;
        mybsockaddr.sin_family = AF_INET;
        mybsock = socket(AF_INET, SOCK_STREAM, 0);
        bind (mybsock, (struct sockaddr *) &mybsockaddr,
sizeof(mybsockaddr));
        close(mybsock);
    }

I do this immediately after the call  usrNetInit(BOOT_LINE_ADRS);  within
the #ifdef INCLUDE_NET_INIT block.  This fix was first posted to tech-talk
in March this year.
