If the issue is specific to AR5416 and power save, then the TIM_TIMER
interrupt might be causing the trouble. You can check whether any
ATH9K_INT_TIM_TIMER interrupt is received in the ath_isr when the
disconnection happens.
This is the hw timer used by the chip to wakeup for  every beacon listen
interval.
