Bug Description
pmtu.sh is a network selftest that was introduced on 4.17. It is currently failing on 4.18. After revert of ccd740cbc6 "vti6: Add pmtu handling to vti6_xmit.", it passes.
The fail is in the nature of holding netdevices refcounts, so some network operations start hanging, including the loading and removal of network modules.

Pushed a revert of d6990976af7c "vti6: fix PMTU caching and reporting on xmit" to fix this temporarily until we have a proper fix.
