>Description:
	A smp kernel is not able to power down a dual cpu system as a
	single cpu kernel does with recent acpi changes. It simply
	stops at the point/message where a single cpu kernel turns off
	the machine:

	  syncing disk...
	  cpu1: CPU 1 ...

	A single (non 'MULTIPROCESSOR') kernel can power down my
	machine.

	I could not test if a 'MULTIPROCESSOR' kernel would also fail
	in powering down a single cpu board...
>How-To-Repeat:
	Boot a smp kernel (on a supported at least dual cpu ;-)
	machine) and try to 'shutdown -p now'.
>Fix:
	Unknown.
