+ bool "Watchdog Timer Support"
+ ---help---
+ If you say Y here (and to one of the following options) and create a
+ character special file /dev/watchdog with major number 10 and minor
+ number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
+ subsequently opening the file and then failing to write to it for
+ longer than 1 minute will result in rebooting the machine. This
+ could be useful for a networked machine that needs to come back
+ on-line as fast as possible after a lock-up. There's both a watchdog
+ implementation entirely in software (which can sometimes fail to
+ reboot the machine) and a driver for hardware watchdog boards, which
+ are more robust and can also keep track of the temperature inside
+ your computer. For details, read
+ <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
+
+ The watchdog is usually used together with the watchdog daemon
+ which is available from
+ <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
+ also monitor NFS connections and can reboot the machine when the process
+ table is full.
+
+ If unsure, say N.

+
+config WATCHDOG_NOWAYOUT

+ it has been started.
