Intel Celeron J1900 watchdog timer

I was wondering if there's a known issue with the watchdog timer that come with Intel Celeron J1900 SoC ? I'm trying to configure it on a Iwill J1900 nano-PC (low cost NUC like PC) and dmesg doesn't show any ichwd device at boot.

If I look again at dmesg, I just saw this error:
Code:
module_register: module isa/ichwd already exists!
Module isa/ichwd failed to register: 17

Hardware watchdog is activated in the BIOS and and working fine (reboot at set time since I can't start watchdogd(8)).

The Iwill PC link (not much details but it's J1900 SoC with Realtek gigabit Ethernet):

It failed to load the second time. You either tried to load the module twice e.g. in loader.conf via the bootloader and in rc.conf via rc.d/kld or compiled into your kernel config.
 
Thanks Crest for the answer.

I will do more tests later since I'm working on something else but I'm pretty sure I removed it from loader.conf and then add it to a custom kernel and build it to check if the result would be the same.

The error you posted indicates a second attempt to load the module, so I would double-check.

There are a number of things that concern me in the console output you posted:
Code:
VT: running with driver "efifb".
Is this running in a VM?
Code:
module_register_init: MOD_LOAD (vesa, 0xffffffff80d9d190, 0) error 19
19 is "Operation not supported by device". Are you doing anything odd in /boot/loader.conf? Can you post the file's contents?
Code:
unknown: I/O range not supported
This is worrisome.
Code:
atrtc0: Warning: Couldn't map I/O.
As is this.
Code:
hdaa0: hdaa_audio_as_parse: Duplicate pin 0 (30) in association 3! Disabling association.
hdaa0: hdaa_audio_as_parse: Pin 30 has wrong direction for association 3! Disabling association.
This may indicate an out-of-date BIOS if running on real hardware, or a hypervisor/configuration issue if running in a VM.
