No /dev/watchdog on NUC7CJYH iTCO_wdt

[LPena1]

I observe the same issue as described /message/495195# 495195 here on NUC6CAYH but this time on NUC7CJYH.

After enabling the watchdog iTCO_wdt module, the device /dev/watchdog is not created.

This device is a Canonical certified hardware for Ubuntu 16.04

Hello lionep

Thank you for joining the community. I see that you are having problems with the Intel® NUC7CJYH, allow me to help you with the inquiries. Allow me to share with you that Intel does not test and validate Intel® NUC on Linux, however, we know that a lot of NUC owners are using it successfully on many different Linux distros. I will suggest you check your Linux distro's website and forums at https://community.ubuntu.com/ https://community.ubuntu.com/ for peer assistance with this issue. Regards,Leonardo C.
