If I enter 'shutdown -p now' the system goes to the message 'acpi0: Entering state 5' then the system freezes, the power button doesn't work and I have to turn off the power supply.Apart from everything else you've mentioned, what happens if you hold down the power button for ~5 seconds when this occurs?
Usually that shuts power down via a "hardware" mechanism (e.g., in a COMBO chip) so I don't know how much diagnostic value it will have in this situation.
