Is there a builtin watchdog timer for the X470 platform? I had a lockup last night that in linux on a system that must be on 24/7. I would like to use a watchdog to force a reboot if that happens again. Before I attempt to purchase one of those $10 to $20 USB watchdog devices I would like to check the status on what AMD provides in its chipset and the chances of enabling it in a 4.17.X kernel (on gentoo using gentoo-sources-4.17.4).


My system is an

AMD Ryzen 2700

ASUS Prime Pro

16GB Crucial DDR4 ECC

WDC Black NVMe 512GB SSD
