The laptop boots fine without acpi. Here is the line number for the panic.
(gdb) l *acpi_pci_link_lookup+0x42
0x3ffc2 is in acpi_pci_link_lookup (/usr/src/sys/modules/acpi/acpi/../../../dev/
acpica/acpi_pci_link.c:590).
585 struct acpi_pci_link_softc *sc;
586 int i;
587
588 ACPI_SERIAL_ASSERT(pci_link);
589 sc = device_get_softc(dev);
590 for (i = 0; i < sc->pl_num_links; i++)
591 if (sc->pl_links[i].l_res_index == source_index)
592 return (&sc->pl_links[i]);
593 return (NULL);
594 }
