It would appear that since introduction of Kernel 6.8 into the daily builds, the installed system fails to carry out a successful reboot or power off when commanded from the desktop or the command line [Symptoms] When selecting either Leave-->Shutdown or Leave-->Reboot from the control panel, the process starts shutting down processes in an orderly fashion, until it gets to the part where it needs to power off hardware, where it hangs. shutdown -H now also fails in the same manner shutdown -r now also fails in the same manner With quiet bootflag disabled, the last system message on display before the hang is "Starting reboot..." or "Starting power-off..." [Workaround] The power button must be pressed for 5 secs to power down the hardware [Possibly related bugs] #1594023 Poweroff or reboot hangs. Laptop won't shutdown. 16.04 #2036987 Laptop Does Not Power Off After Installing Daily Build Of 23.10 [Unsuccessful Workarounds] Tried boot flags acpi=force acpi=nocrq reboot=pci suggested in #1594023 - No effect [Observations] I do believe that shutdown/reboot was working correctly on a live USB Lubuntu Noble Numbat Alpha build on the same hardware downloaded 22-Feb-2024. This release had an earlier kernel than 6.8. Sadly i no longer have the .iso to confirm this. All Lubuntu Noble daily builds since kernel 6.8 was introduced appear to exhibit the symptoms as above [System info] Operating System: Ubuntu Noble Numbat (development branch) Kernel: Linux 6.8.0-11-generic Architecture: x86-64 Hardware Vendor: Dell Inc.
