John, I've identified the problem. Here is his MADT:
Type=Local APIC
ACPI CPU=0
APIC ID=0
Type=Local APIC
ACPI CPU=1
APIC ID=1
Type=Local APIC
ACPI CPU=2
APIC ID=0
Type=Local APIC
ACPI CPU=3
APIC ID=0
And here are his Processor objects:
Scope (\_PR)
{
Processor (CPU1, 0x01, 0x00000410, 0x06) {}
Processor (CPU2, 0x02, 0x00000410, 0x06) {}
Processor (CPU3, 0x06, 0x00000410, 0x06) {}
Processor (CPU4, 0x07, 0x00000410, 0x06) {}
}
So all the ACPI CPU ids don't match between the MADT and the Processor
object. I'm not sure what to do to solve this.
