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.

Here this same blacklist entry breaks some functionality for a Thinkpad T41. In turn, that bug includes a reference to another source (http://permalink.gmane.org/gmane.linux.drivers.i2c/9120) where the blacklist entry has required support effort. lsb_release -rd Description: Ubuntu 15.04 Release: 15.04 apt-cache policy kmod kmod: Installed: 18-3ubuntu1 Candidate: 18-3ubuntu1 Version table: *** 18-3ubuntu1 0 500 http://au.archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kmod/+bug/1475945/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
