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

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

1066 This is the driver for the hardware watchdog found on the IEI
1067 single board computers EPIC Nano 7240 (and likely others). This
1068 watchdog simply watches your kernel to make sure it doesn't freeze,
1069 and if it does, it reboots your computer after a certain amount of
1070 time.
