Re-read my post. I didn’t say that.
But a HW watchdog does not help if your problem is in any of the other layers. It won’t trigger if e.g. your kernel is still running (you say host reponds to pings so the HW isn’t locked up).
Sure there are already or can be setup more watchdogs on the other levels such as the one in systemd, but you asked for the HW watchdog in the processor. That one won’t help with your problems.
Either way, to have one or even more working watchdogs is no proper solution to your problem.
Finding and fixing the root cause is the only right way.
We can talk a lot and make the suggestions about problem, about layers and kernels and so on! But what for?
I have just installed it in 5 mins and not after hangup - it works! The only thing what i need from it - reboot if im not at home! Made!
And finding a solution about the hangup - is the question of another thread
