If powersave is enabled and there are any transitions to network or full sleep - even if they're pretty damned brief - eventually something messes up somewhere and the bus glue between the AR9331 SoC and the AR9331 wifi stops working. It shows up as stuck DMA and LOCAL_TIMEOUT interrupts. Both ath9k and the reference driver does a full chip reset if things get stuck. So: * teach the AR9330 HAL about the force_full_reset option I added a couple of years ago; * if the chip is currently in full-sleep, do a full-reset; * if TX DMA and/or RX DMA are still enabled (eg, they did get stuck during reset) then do a full-reset. Tested: * AR9331 SoC, STA mode |
