>Description:

	This workstation - an HP dc5750 panics if you try and boot with ACPI
	enabled. I realise that there is another problem with these machines
	relating to the SMAP as reported in 111952, but this appears to
	be different. I see the SMAP probelem if I boot in amd64 (with or
	without ACPI enabled) but under i386 it simply panics before even
	getting to that stage.

	I am using the latest BIOS from HP, and a version of -STABLE
	from two days ago (November 6th).


>How-To-Repeat:

	Attempt to boot a 6.3 kernel on one of these machines with ACPI
	enabled.
	
>Fix:

	Disabling ACPI enables the machine to boot - but it then requires
	the amount of physical memory to be set by hand in loader.conf 
	and cannot see the 2nd processor.

 This is probably the same bug as 119716 and thus should be fixed by  
 the patch in the mailing list post:
