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

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

774 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.

776 Entering BIOS setup temporary disables watchdog operation regardless to current state,
777 so system will not be restarted while user in BIOS setup.

1068 single board computers EPIC Nano 7240 (and likely others). This
1069 watchdog simply watches your kernel to make sure it doesn't freeze,
