Looks like some potentially nice ath9k patches just got merged into wireless-testing. It has been stable and fast so far, but I do still see DMA issues in the logs. This is on a system with 30 STAs associated with a flakey netgear running HT40-, and 30 associated with a cisco running HT20. (Through some luck, the netgear managed to send proper ht-info channel this time, so the NIC went HT40-). ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 sta0: authenticate with 30:46:9a:10:0b:9a (try 1) sta0: authenticated sta0: associate with 30:46:9a:10:0b:9a (try 1) sta0: RX ReassocResp from 30:46:9a:10:0b:9a (capab=0x421 status=0 aid=31) sta0: associated ieee80211 wiphy0: Allocated STA 30:46:9a:10:0b:9a ieee80211 wiphy0: Inserted STA 30:46:9a:10:0b:9a ieee80211 wiphy0: WMM queue=2 aci=0 acm=0 aifs=3 cWmin=15 cWmax=1023 txop=0 uapsd=0 ieee80211 wiphy0: WMM queue=3 aci=1 acm=0 aifs=7 cWmin=15 cWmax=1023 txop=0 uapsd=0 ieee80211 wiphy0: WMM queue=1 aci=2 acm=0 aifs=2 cWmin=7 cWmax=15 txop=94 uapsd=0 ieee80211 wiphy0: WMM queue=0 aci=3 acm=0 aifs=2 cWmin=3 cWmax=7 txop=47 uapsd=0 ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ADDRCONF(NETDEV_CHANGE): sta0: link becomes ready sta0: no IPv6 routers present ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 Thanks, Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
