 =46rom what I can tell: (I had to use objdump -d, gdb did not output =
 anything)
 
 0xc046c09c is in acpi_madt_walk(), calling __x86_indirect_thunk_edi()
 0xc04c6fab is in mpacpi_scan_apics(), calling api_madt_walk()
 0xc0138df9 is in mainbus_attach(), calling mpacpi_scan_apics()
 
 It seems to be consistent; does it help?
 
 Cheers,
