Try this:

for i in s u b; do echo $i | sudo tee /proc/sysrq-trigger; sleep 5; done # reboot no matter the state

for i in s u o; do echo $i | sudo tee /proc/sysrq-trigger; sleep 5; done # shutdown the system even when it is in a hanged state

Is there a script for a rig offline telegram notification that Im missing? The telegram messages are awesome, but would be good to know if it powers down and stay down.

If system is going to be rebooted you will get notified from script that send the reboot command (watchdog or temp control), but if your rig freeze there is nothing to do.
You can set up an external watchdog like an RPi to check your rigs ping and ssh port and send you message if they were unreachable.

Hi
About this, does nvOC use the linux kernel watchdog ?

Unfortunately no.
Actually a card in one of my rigs making it hard freeze lately and I was reading and playing with sysctl to do a reboot on kernel panic with no success.

I changed

Code:

sudo reboot

in both watchdog and temp control to

Code:

sudo systemctl reboot --force

Didnt helped a bit.

Also added to /etc/sysctl.conf

Code:

kernel.panic = 1

And no help too,
The system freezes after 3-4 days of running clean with no logs, just a hard freeze.

Any one has good ideas to implement linux hardware kernel watchdog would be amazing to add ...

Thanks mate
Problem is system freezes and wont get to run those.
I need to enable kernel watchdog so it can reboot the frozen system.
