Public bug reported: I dual boot Ubuntu 23.10 from openzfs from nvme (main OS) and from ext4 from HDD (backup OS). In 23.10 everything worked, I could use my datapools on both systems also rpool, The nvme datapool rpool contains the ROOT dataset and 2 datasets with my main VMs.
I upgraded the ext4 system to 24.04 (do-release-upgrade -d) and that worked fine. I have 2 other datapools on the HDD and I can use them without any issue after (zpool import -f) on the ext4 system. As soon as I try to import the datapool rpool the problem starts, it gives the following error message: "Broadcast message from systemd-journald@Host-sdb5 (Sat 2024-03-09 12:50:47 AST): systemd[1]: Caught <ABRT>, from our own process." Afterwards it is impossible to use the terminal, it just does not start. However most other applications still work as normal. It is also impossible to shut-down the system from the menu. I have to power off the system with the power button. On reboot I get the following error messages; zfs: module license "CDDL" taints kernel. Disabling lock debugging due to kernel taint zfs: module license taints kernel It seems to load the zfs kernel modules again, why? It is superfluous and wrong, because they are already loaded from ext4 much earlier. Afterward the system is completely confused and hangs. (see the annexed photo) My nvme system does not boot anymore, because it is missing rpool, but it nicely advises in initramfs to use "zpool import -f" and that works.
