De acordo com man watchdog.conf
:
interval = <interval> Set the highest possible interval between two writes to the watchdog device. Default value is 1 second. The kernel drivers expects a write command every minute. Otherwise the system will be rebooted. Therefore an interval of more than a minute can only be used with the -f command-line option.
Como definir o que 'os drivers do kernel esperam'? O que a opção de linha de comando '-f' deve fazer?
