10 character special file /dev/watchdog with major number 10 and minor
11 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
12 subsequently opening the file and then failing to write to it for
13 longer than 1 minute will result in rebooting the machine. This
14 could be useful for a networked machine that needs to come back

22 The watchdog is usually used together with the watchdog daemon
23 which is available from

25 also monitor NFS connections and can reboot the machine when the process

769 It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
770 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
771
772 Entering BIOS setup temporary disables watchdog operation regardless to current state,
773 so system will not be restarted while user in BIOS setup.
774
775 Once watchdog was enabled the system will be restarted every

1531 to have watchdog support enabled, say Y, otherwise say N.
1532
1533 As a side note, saying Y here will automatically boost HZ to 1000
1534 so that the timer has a chance to clear the overflow counter. On
1535 slower systems (such as the SH-2 and SH-3) this will likely yield
1536 some performance issues. As such, the WDT should be avoided here
