Xin, I'm under the impression that bce_intr() might be called when
IFF_DRV_RUNNING is not set. Could you check whether
sc->bce_ifp->if_drv_flags set IFF_DRV_RUNNING in bce_intr()?
Sorry, one of my box that can host quad-port bce(4) controller died
so I can't verify this at the moment until I get a new MB.
