I still have a related problem, not in every shutdown but it is still recurrent.Despite have done the "ACPI Configuration" change in the UEFI.
My system doesn't shutdown at all, it hangs and i have to turn it off pressing the power button.
Here is a relevant part from from my last failed shutdown log, I added the 'debug' option to the kernel line in grub.
This is directly related to the use of a new usb keyboard, using an os/2 keyboard fixes this shutdown problem so im pretty sure it is the same problem discussed here.
