       The  viawd  driver  provides  watchdog(4)  support  for the watchdog interrupt timer present on VIA south
       bridge chipset (VT8251, CX700, VX800, VX855, VX900).

       The VIA south bridge have a built-in watchdog timer, which can be enabled and disabled by user's  program
       and set between 1 to 1023 seconds.

       The viawd driver when unloaded with running watchdog will reschedule the watchdog to 5 minutes.

       The viawd driver first appeared in FreeBSD 10.0.
