 Hrm, this doesn't make a whole lot of sense:
 (gdb) l *0xc0175864
 0xc0175864 is in cas_pci_attach (/usr/src/sys/dev/cas/if_cas.c:356).
 351                     switch (sc->sc_variant) {
 352                     default:
 353                             sc->sc_phyad = -1;
 354                             break;
 355                     }
 356                     error = mii_phy_probe(sc->sc_dev, &sc->sc_miibus,
 357                         cas_mediachange, cas_mediastatus);
 358             }

 Except maybe that this is triggered by the bus_space_write_4() above
 that, which is cas_pci_attach+0xc80, and somehow delayed. Is this the
 MMF (multimode fibre) model of the GigaSwift Ethernet 1.0 card perhaps?
 Can you boot with that card removed?
