From 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,
