It helps a bit, if you modify the driver not to reinit, but to just reset t=
he=20
card:
change=20
static void
ath_tx_timeout(struct net_device *dev)
{
        struct ath_softc *sc =3D dev->priv;
        sc->sc_stats.ast_watchdog++;
#ifdef AR_DEBUG
        if (ath_debug)
                ath_hal_dumpstate(sc->sc_ah);
#endif
        ath_init(dev);
}

static void
ath_tx_timeout(struct net_device *dev)
{
        struct ath_softc *sc =3D dev->priv;
        sc->sc_stats.ast_watchdog++;
#ifdef AR_DEBUG
        if (ath_debug)
                ath_hal_dumpstate(sc->sc_ah);
#endif
        ath_reset(dev);
}
in driver/if_ath.c

This takes "just" 3 sec.

Same here. even switched to apm. No chance.

strange, relly. But at least it's the same bug i see.

I even got:
           CPU0
  0:     532251          XT-PIC  timer
  1:       2065          XT-PIC  i8042

but not better.
