This script is a backport from newer hw-management package. Chaning it here means we need to change default in hw-management package in master. I suggest to change this in sonic-utlitiies, you can call this script like this:
hw-management-wd.sh start 180

Reduced the default watchdog timeout to 3 mins.

Wait for 3 minutes and see if the device reboots
