xnf0: tx stuck: prod

[Zbyszek Żółkiewski]

Hi,

OpenBSD 6.2 GENERIC.MP#134 amd64 running on Xen (AWS), anyone experienced this: 

xnf0: tx stuck: prod 3722866 cons 3722866,3722865 evt 3722867,3722866
xnf0: tx stuck: prod 3903774 cons 3903774,3903773 evt 3903775,3903774
xnf0: tx stuck: prod 5736476 cons 5736476,5736475 evt 5736477,5736476
xnf0: tx stuck: prod 5796678 cons 5796678,5796677 evt 5796679,5796678
xnf0: tx stuck: prod 5821071 cons 5821071,5821070 evt 5821072,5821071

that is from if_xnf.c:

xnf_watchdog(struct ifnet *ifp)
{
        struct xnf_softc *sc = ifp->if_softc;
        struct xnf_tx_ring *txr = sc->sc_tx_ring;

        printf("%s: tx stuck: prod %u cons %u,%u evt %u,%u\n",
            ifp->if_xname, txr->txr_prod, txr->txr_cons, sc->sc_tx_cons,
            txr->txr_prod_event, txr->txr_cons_event);
}

anyone had that problem and found cause of this “stucks” ?
