I’m trying to setup the watchdog on Ubuntu Server. Currently I’m using a software watchdog, via the softdog module, however, I would like to take advantage of the hardware watchdog on the ASRock Rack EPYCD8-2T motherboard. But I need to know which kernel module to use to do that.
Does anyone know?
I take it you’ve already found (and read 
) these links?
