C'est pas à ça que servent les cartes watchdog, dont pas mal sont supportées par linux.
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 online 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 Documentation/watchdog.txt
