>Description:
	GENERIC.MPACPI with the -current sources from 2006-08-06 for i386
	hangs on an NForce4 motherboard with Athlon 64 X2.
	It boots, configures most of the system, configures the raidframe and
	prints
		"cpu1: CPU 1 running". Then it hangs.

	I cannot even enter the debugger. This happens with every current
	source since the introduction of the "new" ACPI system around late
	june. Before this the boot continued with the configuration of
	wsdisplay0. I cannot tell if it enters userland.
>How-To-Repeat:
	Boot an GENERIC.MPACPI on NForce4 with Athlon 64 X2. Watch it hang.
>Fix:
	none known 8-( This is a real showstopper for over a month now for me.
