Lubuntu 24.04 LTS, when persistent live by mkusb-plug does not shut down properly

I am testing the mehods of mkusb to create USB boot drives of Lubuntu 24.04 LTS.

  • Live (live-only) systems made by cloning work well as expected (and this kind of system is the standard for USB boot drives).

  • Persistent live systems

    • by dus-persistent

      • In older computers work well both in UEFI mode and BIOS mode (also in UEFI mode with secure boot).
      • In newer computers work well except with secure boot and other new hardware/software means to prevent booting.
    • by dus-iso2usb work well both in UEFI mode and BIOS mode (also in UEFI mode with secure boot in newer computers).

    • by mkusb-plug can work well both in UEFI mode and BIOS mode (also in UEFI mode with secure boot in newer computers).

      • However, the shutdown behaviour depends on the USB drive. It works well with a fast SSD connected via USB, but in a slower USB3 pendrive (e.g. Corsair Voyager GT USB 3.0) it will cause kernel panic. The drive will not be corrupted afterward, but you must shut down by pressing the power key for several seconds.

        There is a workaround: If you press Enter, when ‘adviced’ to do so according to the output to the screen, it will shutdown properly. But if you wait for a few seconds, things will go wrong.
