: 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 }
Weird. sc has to be null here for this to fail at that line...
