Many devices can generate a wake-up signal after the computer is shut
down (wake on LAN, wake on key, etc.) and this is evidently happening
when it should not.  So it is hardware-related but probably caused by a
change in the way a driver prepares the hardware for shutdown.

Please try to work out which driver is doing this, by removing a driver
with the 'rmmod' command and then shutting down.  I think it is probably
one of:

e1000e
igb
xhci_hcd
ehci-pci
