I have found that iTCO_wdt doesn't work without previously loading i2c-i801 (you can see a pair of references in http:// linux-kernel. 2935.n7. nabble. com/PATCH- 0-5-iTCO- wdt-Add- support- for-Intel- Sunrisepoint- td1160031. html and in https:/ /lkml.org/ lkml/2016/ 9/10/157) As it's blacklisted, it doesn't load even when putting it on /etc/modules.
As stated by OP on launchpad discussion, it seems that the original decission to blacklist i2-i801, as correct as it was in its moment, seems to be creating more problems now for modern systems.
