Thanks Yokota-san for tracking down the problem.

And if such a problem was found, please send ACPI data with the
report. This is very useful info. for our debugging.
To get ACPI data,
# acpidump -o foo.dsdt > foo.asl
and send both files to acpi-jp@. See also acpidump(8).

I personally, don't have enough time to hack the code for now (sorry),
but I think that newly added `placeholders' code causes the problem
for my first impression.
for (i = 0; i < 100; i++) {
rid = i;
res = bus_alloc_resource(dev, SYS_RES_IOPORT, &rid, 0, ~0, 1, 0);
rid = i;
res = bus_alloc_resource(dev, SYS_RES_MEMORY, &rid, 0, ~0, 1, 0);
rid = i;
res = bus_alloc_resource(dev, SYS_RES_IRQ, &rid, 0, ~0, 1, 0);
}
Mike, do you have any idea on this?
Anyway, Yokota-san thank you very much for finding a workaround.
