So it looks like it fails to talk to the switch.

The only thing I can think of at this moment is announcement of next page in auto negotiation. atphy(4) does not directly manipulate master/slave, single port/multi port configuration and this configuration may need next page if other link partner also announces next page capability. Try attached patch and let me know whether this makes any difference for you. You may have to cold boot the box because stock driver used to clear next page bit in auto-negotiation. > ./danfe --4Ckj6UjgE2iN1+kY Content-Type: text/x-diff; charset=us-ascii Content-Disposition: attachment; filename="atphy.anar.diff" Index: sys/dev/mii/atphy.c =================================================================== --- sys/dev/mii/atphy.c (revision 265477) +++ sys/dev/mii/atphy.c (working copy) @@ -338,7 +338,9 @@ atphy_setmedia(struct mii_softc *sc, int media) { uint16_t anar; - anar = BMSR_MEDIA_TO_ANAR(sc->mii_capabilities) | ANAR_CSMA; + anar = PHY_READ(sc, MII_ANAR); + anar &= ANAR_NP; + anar |= BMSR_MEDIA_TO_ANAR(sc->mii_capabilities) | ANAR_CSMA; if ((IFM_SUBTYPE(media) == IFM_AUTO || (media & IFM_FDX) != 0) && ((media & IFM_FLOW) != 0 || (sc->mii_flags & MIIF_FORCEPAUSE) != 0)) --4Ckj6UjgE2iN1+kY--
