- *		use the Linux watchdog API
- *
- *      The Watchdog is configured to reset the MTX-1
- *      if it is not triggered for 100 seconds.
- *      It should not be triggered more often than 1.6 seconds.
- *
- *      A timer triggers the watchdog every 5 seconds, until
- *      it is opened for the first time. After the first open
- *      it MUST be triggered every 2..95 seconds.
