I am not sure if that's what you mean, but if I set "iwconfig wlan0 power off" it makes no difference. > I suggest modifying ath_intr() so if there is an interrupt storm, > disable _all_ sources of interrupts (ie, set sync_cause, async_cause > to 0, set imr to 0, set ier to 0) and see if it continues occuring.

I am now calling ath9k_hw_ops(sc->sc_ah)->config_pci_powersave(sc->sc_ah, true); ath9k_setpower(sc, ATH9K_PM_FULL_SLEEP); right before request_irq, and the interrupts still come. And the device is in FULL_SLEEP the whole time, at least according to ah->power_mode.
