Re: kern/42114: iwn0: could not lock memory

[David DEMELIER <demelier.david%gmail.com@localhost>]

Maybe this :

/*
 * Grab exclusive access to NIC memory.
 */
static void
iwn_mem_lock(struct iwn_softc *sc)
{
  uint32_t tmp;
  int ntries;

  tmp = IWN_READ(sc, IWN_GPIO_CTL);
  IWN_WRITE(sc, IWN_GPIO_CTL, tmp | IWN_GPIO_MAC);

  /* spin until we actually get the lock */
  for (ntries = 0; ntries < 1000; ntries++) {
    if ((IWN_READ(sc, IWN_GPIO_CTL) &
      (IWN_GPIO_CLOCK | IWN_GPIO_SLEEP)) == IWN_GPIO_CLOCK)
      break;
    DELAY(10);
  }
  if (ntries == 1000)
    aprint_error_dev(sc->sc_dev, "could not lock memory\n");
}

in /usr/src/sys/dev/pci/if_iwn.c
