Solved. And likewise are #2080355, #2088532, #2085734, minimum. Here is the background: Since *buntu (and derivates) became completely useless due to continuous self-resets, no way to start, no shutdown nor poweroff after sudo poweroff, and uninterruptible spontaneous shutdowns, and a times using the volume rocker for a cold boot, I had no alternative but to switch to fedora (41), which didn't show these things at all at the time of migration. Some months into it, I encountered the identical trouble on F41. With the help of the nice people over there, we could find, that rolling back fwupd to the previous version solved all this mess completely. Booting to the previous installation (kubuntu), the same crap was encountered again (including cleaning nvram in UEFI, only to find it overrun again at the subsequent boot), the next full upgrade (which included an upgrade of fwupd) also solved the identified problems for good. Now all machines once again work perfectly okay once again.
Make this a 'silent bug rectification', since I am not sure that the nice people working on fwupd were ever aware of this bug (at least affecting lenovo thinkpad Helix 2), or not. I do think, that - should anyone ever run into this - a complete description (and remedy) as given here could be helpful. ** Changed in: systemd (Ubuntu) Status: Invalid => Fix Released ** Package changed: systemd (Ubuntu) => fwupd (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/2078572 Title: "Restart" doesn't restart after release upgrade 22.04 to 24.04 Status in fwupd package in Ubuntu: Fix Released Bug description: After my upgrade from 22.04 to 24.04, it is impossible to "Restart" the laptop. While "Shut Down" works, "Restart" hangs with the 'machine screen', in my case white "lenovo" on a black background, forever. The journalctl shows this: No activity between 13:45 and 14:27, while the "lenovo" screen was shown, until I forcible pressed the 'Power Off' around 14:27.
