It is supposed to automatically reboot hanged systems due to unrecoverable software errors. The watchdog module is specific to the hardware or chip being used. Personal computer users don’t need watchdog as they can reset the system manually. However, it is useful for systems that are mission critical and need the ability to reboot themselves without human intervention. For example, servers on a remote location or embedded equipment on a spacecraft that need automatic hardware reset capabilities. Watchdog daemon should start at boot time and put itself in the background. You can check if it is running: ps -af | grep watch* If the kernel is NOT compiled with CONFIG_WATCHDOG_NOWAYOUT, then if you close the /dev/watchdog properly, it will not cause a reboot. You can write the character V into /dev/watchdog and then close the file. This should stop the watchdog. # enddoc
