>Description:
      I try watchdogd.  wachdogd does not stop the timer in the kernel when exitting, kernel panics during long shutdown process.

>How-To-Repeat:
1. make kernel with SW_WATCHDOG
2. reboot
3. /usr/sbin/watchdogd -d
4. SIGINT
5. panic after 15 secs.

>Fix:
watchdog_onoff(int onoff)
{
        if (onoff)
                timeout |= WD_ACTIVE;
        else
                timeout = WD_TO_NEVER; /*FIX*/
        return watchdog_patpat();
}
