This looks likely to be some kind of incompatibility with full-disk encrypted systems. I just spotted that the errors I am getting are not about the swap partition at all, but instead about /dev/mapper/xubuntu --vg-root, which is the encrypted root. From /etc/fstab:
/dev/mapper/xubuntu--vg-root / ext4 errors=remount-ro 0 1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768230 Title: Long time booting : Failed to connect to lvmetad.
