Symptoms:
	PHKL_25494:
	( SR:8606218389 CR:JAGad87538 )
	Spurious diagnostic messages fill up the message buffer.
	The message might look like: Line 821 in
	/ux/core/kern/em/plat/nec/azusa/azusa_psm.c:
	AzusA_azusa_put_chassis : SAL_PSM failed. ret[0] =
	0xfffffffffffffffd. ret[1] = 0xfffffffffffffffd.
	ret[2] = 103f2fc7"

	PHKL_24784:
	( SR:8606198467 CR:JAGad67657 )
	A panic during boot, from init(1m) exiting, occurs when cell
	0 is not configured on a u16000.  The stack trace would look
	similar to the following:

	panic: init died
	Stack Trace:
	  IP                  Function Name
	  0xe00000000047e670  exit+0xff0
	  0xe00000000049a720  rexit+0x40
	  0xe000000000445bb0  syscall+0x4b0

Defect Description:
	PHKL_25494:
	( SR:8606218389 CR:JAGad87538 )
	Spurious printf's fill up message buffer with
	diagnostics messages.

	Resolution:
	The resolution is to change the way the printf's
	are displayed.  The code was changed so that the
	put_chassis call that was failing would not
	timeout and display its error messages. The
	put_chassis call now functions asynchronously
	rather than synchronously.

	PHKL_24784:
	( SR:8606198467 CR:JAGad67657 )
	The CORE I/O card was incorrectly associated with cell 0 on
	the u16000.  If cell 0 is not configured the CORE I/O card
	is not scanned, and the required CORE I/O devices are not
	detected.  The fact that some of these devices are not found
	causes the init(1m) prcess to exit which results in a system
	panic.

	Resolution:
	The CORE I/O card is now scanned even if cell 0 is not
	configured.
