Sometimes ath0 gives tiemout when transmitting to 802.11g client. The higher is speed the higher is tiemouts frequency. When environment is noisy, speed is low and timeouts is rare. When environment is clean, speed is high (up to 2.5MiB/s) but timeouts are frequent. Here is output of `dmesg' when reset debug is enabled. ath0: stuck beacon; resetting (bmiss count 4) ath0: ath_reset: called ath0: ath_stoptxdma: tx queue [9] 0x1b9b000, link 0 ath0: ath_tx_stopdma: tx queue [0] 0, link 0 ath0: ath_tx_stopdma: tx queue [1] 0x212fb40, link 0 ath0: ath_tx_stopdma: tx queue [2] 0, link 0 ath0: ath_tx_stopdma: tx queue [3] 0, link 0 ath0: ath_tx_stopdma: tx queue [8] 0x20beb40, link 0 ar5212StopDmaReceive: dma failed to stop in 10ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 ath_stoprecv: rx queue 0x1b96480, link 0xcdb96420 ath0: stuck beacon; resetting (bmiss count 4) ath0: ath_reset: called ath0: ath_stoptxdma: tx queue [9] 0x1b9b000, link 0 ath0: ath_tx_stopdma: tx queue [0] 0, link 0 ath0: ath_tx_stopdma: tx queue [1] 0x20bc780, link 0xd58c6420 ath0: ath_tx_stopdma: tx queue [2] 0, link 0 ath0: ath_tx_stopdma: tx queue [3] 0, link 0 ath0: ath_tx_stopdma: tx queue [8] 0x20fe3c0, link 0 ath_stoprecv: rx queue 0x1b90660, link 0xcdb90600 ath0: device timeout ath0: ath_reset: called ath0: ath_stoptxdma: tx queue [9] 0x1b9b000, link 0 ath0: ath_tx_stopdma: tx queue [0] 0, link 0 ath0: ath_tx_stopdma: tx queue [1] 0x20c63c0, link 0xd58b5060 ath0: ath_tx_stopdma: tx queue [2] 0, link 0 ath0: ath_tx_stopdma: tx queue [3] 0, link 0 ath0: ath_tx_stopdma: tx queue [8] 0, link 0 ath_stoprecv: rx queue 0x1b94d20, link 0xcdb94c00 R[ 0] (DS.V:0xcdb94c60 DS.P:0x1b94c60) L:01b94cc0 D:18d33000 !
