This issue was first observed on an AP121 and the WAR is enabled for AR9340 also (DB120 etc.), since it uses a PLL design identical to AR9330. This is not required for AR9485 and AR9550. Various bugs have been reported regarding this: https://bugzilla.redhat.com/show_bug.cgi?id=997217 https://bugzilla.redhat.com/show_bug.cgi?id=994648 Cc: stable@vger.kernel.org Signed-off-by: Sujith Manoharan --- drivers/net/wireless/ath/ath9k/main.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/net/wireless/ath/ath9k/main.c b/drivers/net/wireless/ath/ath9k/main.c index ac9f18f..e4f6590 100644 --- a/drivers/net/wireless/ath/ath9k/main.c +++ b/drivers/net/wireless/ath/ath9k/main.c @@ -173,8 +173,7 @@ static void ath_restart_work(struct ath_softc *sc) { ieee80211_queue_delayed_work(sc->hw, &sc->tx_complete_work, 0); - if (AR_SREV_9340(sc->sc_ah) || AR_SREV_9485(sc->sc_ah) || - AR_SREV_9550(sc->sc_ah)) + if (AR_SREV_9340(sc->sc_ah) || AR_SREV_9330(sc->sc_ah)) ieee80211_queue_delayed_work(sc->hw, &sc->hw_pll_work, msecs_to_jiffies(ATH_PLL_WORK_INTERVAL)); -- 1.8.3.4
