ACPI is silent about the CPU IDs in the processor object. In all three
systems where I tested this the range started from 0. So now these systems
hit the included assertion:
struct cpu_info *ci;
KASSERT(id != 0);
This is a known issue. No clean solution exist in any implementation I am
aware of. The IDs may also vary between the processor object and MADT.
In essence, however, this is not so much of an issue because the essential
information should be uniform across CPUs.

Can I see the DSDT of this laptop (see acpidump(8))? Due to the reasons with
the identification, I think we might want to attach them all nevertheless.
