Symptoms:
	PHKL_30044:
	( SR:8606321513 CR:JAGae83981 )
	There is a memory leak in the hardware scan of the Core Bus.
	The Core Bus is on D, K, and J class PA systems. Over time,
	the memory leak will degrade performance. The leakage rate
	is one word per execution of the ioscan command.

Defect Description:
	PHKL_30044:
	( SR:8606321513 CR:JAGae83981 )
	The ioscan function triggers a hardware scan of the system.
	The scan of the Core Bus on a D, K, or J class PA system
	causes a 1 word memory leak.

	Resolution:
	The allocation of the memory is modified so that the memory
	will be freed appropriately.

Enhancement:
