How can I find lost CPU1 in Sun V20Z ?

I compiled with SMP option with "make kernel KERNCONF=MYKERNEL" in
/usr/src $(TOP) derective of source tree but the kernel comes panic with
"CPU1 Launched !" message. Whenever I put in SMP option with MYKERNEL,
the kernel comes panic. Is there any successful story with SMP option in
V20Z ?
I am suspicious that why even GENERIC KERNEL can't find CPU1?

MyKernel configuration file SMP option for AMD64

# Workarounds for some known-to-be-broken chipsets (nVidia
device		atpic		# 8259A compatability
options 	NO_MIXED_MODE	# Don't penalize working chipsets

# Bus support.  Do not remove isa, even if you have no isa slots
options	        SMP
device		acpi
options         ACPI_DEBUG
options         ACPI_MAX_THREADS=1
device		isa
device		pci

Below messages are only one CPU option
