Thanks for testing the upgrade to 19.10. The only reason you would boot with an older version of a kernel and zfs itself is due to your update between 19.04 to 19.10 failed. Can you share the upgrade logs /var/log/upgrade content and /var/log/dist-upgrade?
The weird part is that do-release-upgrade would have warned you about a failed upgrade.
