Interrupt storm on acpi0 occurred after madt.c change

Hi.
I've experienced interrupt storm on acpi0 after your v1.10 madt.c commit.
(which is located at src/sys/i386/acpica/madt.c);
What really makes me frustrating is this storm wasn't here before 1.10 change,
which is exactly stand against your commit log message. :-(
I've recompiled kernel with v1.9 of madt.c and the problem didn't occur.

I'm using ASUS P2B-D with two p3-650 processors.
BIOS version is 1014 beta 3 (which is the last published one);

My kernel config is stripped GENERIC, which includes
option	CPU_FASTER_5X86_FPU
option	CPU_ENABLE_SSE
device	acpi		# Mine hangs with acpi loaded as module.

Attached file is my acpidump -t -d output.
Thanks.
