9 If you say Y here (and to one of the following options) and create a
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
24 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
25 also monitor NFS connections and can reboot the machine when the process

1447 interrupt. On first expiration of the watchdog, the
1448 interrupt handler pokes it. The second expiration causes an
1449 NMI that prints a message. The third expiration causes a
1450 global soft reset.

1696 so that the timer has a chance to clear the overflow counter. On
1697 slower systems (such as the SH-2 and SH-3) this will likely yield
