I need to get a kernel which boots first. It will take some time, as I
need to test some stuff first.

Not sure how to get kernel dump, but because it was near to begin of
this function, I added a printf():
ACPI_SERIAL_BEGIN(pci_link);
sc =3D device_get_softc(dev);
printf("sc=3D%p\n", sc);
KASSERT(index >=3D 0 && index < sc->pl_num_links,
("%s: invalid index %d", __func__, index));
And I get:
sc=3D0
just before panic.
