commit 79223ca1f57776d2770da9561c26cc2f2dd42205 upstream.

Enable RWDT and use 60 seconds as default timeout.
So this will reboot machine if userspace does not ping it within 60 seconds by
default?
Yes, if you enable watchdog in user space and there is no ping activity for 60 sec.
We can verify this by using the below command
Aha. But if userspace does nothing, no reboot happens. Good.

Best regards,
Pavel
