MSI B350M MORTAR, MSI B350 TOMAHAWK, and Gigabyte AB350M-Gaming 3. CPU is Ryzen 1700X on all boards. On the MSI boards, the watchdog is reported as disabled. Enabling it and letting it expire does not have an effect. I am using the Super-IO watchdog instead on those boards (and it works). On the Gigabyte board, the watchdog is reported as enabled, and it works (and the watchdog on the Super-IO chips does not work). Feel free to play with the driver. Maybe there is a means to enable the watchdog if it is disabled. Unfortunately, I was unable to figure out how to do it, so I thought it is better to report the fact and not instantiate the watchdog if it doesn't work.
