Note that relaxing the watchdog module blacklist would solve this issue too: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1767172.

Is pc-kernel supposed to skip shipping those? Should there be modprobe.d in the core20 snap that prevents these known modules from loading by default? Also I'm not too sure about the watchdog modules exclusion, given that systemd can operate watchdogs by default, hence it shouldn't be too dangerous to autoenable them?
