C2750D4I Hardware watchdog does show up, still resets the system

Related: https://bbs.archlinux.org/viewtopic.php?id=216457

Even with UEFI version 3.20 (file C275D4I3.20) the broken hardware watchdog is still not fixed: system resets despite having "watchdog-device = /dev/watchdog" in /etc/watchdog.conf and the service enabled and running:

This AsRock Rack board gets these IPMI modules loaded and watchdog.service seems to run ok:

# lsmod | grep ipmi
ipmi_ssif              32768  0
ipmi_si                65536  0
ipmi_devintf           20480  0
ipmi_msghandler        65536  3 ipmi_devintf,ipmi_si,ipmi_ssif

# systemctl status watchdog.service

There seem to be 2 watch dog devices available:

# ls -la /dev/watch*
crw------- 1 root root  10, 130 Dec 24 01:52 /dev/watchdog
crw------- 1 root root 246,   0 Dec 24 01:52 /dev/watchdog0

Watchdog is version 5.15;  Variable 'realtime' found as 'yes' = 1; Integer 'priority' found = 1.

Is doesn't matter which one is configured in /etc/watchdog.conf, the system resets itself after 5 minutes.

Has anyone got the NMI hardware watch dog on AsRock Rack C2750D4I boards working as expected?
