In the boot log, i saw "adi_wdt: initialized: timeout=20 sec (nowayout=0)",
but how to test whether the watchdog is really work to protect my system?
and in the /etc/init.d/S15watchdog file,
echo "Starting watchdog..."
watchdog -t 5 /dev/watchdog
i changed it to
watchdog -t 5 -T 2 /dev/watchdog
which means it shoud reboot after 2 seconds if no reset,
but it did not reboot , which confused me, how to test the watchdog?
