No /dev/watchdog on NUC7CJYH iTCO_wdt


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.

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 for peer assistance with this issue.
