Hello, I'm trying to create mesh-network on routerstation pro with ar71xx and atheros 5213A,using openwrt backfire and ath5k. After "iw dev wlan0 interface add mesh type mp mesh_id mymesh","ifconfig mesh up" paralyse the all network orders, I can see "ifconfig" "iwconfig" are dead with "ps",and I cannot kill them. I look up errors in "dmesg", It says the last functions is ath5k_hw_init_beacon() .I add some mdelay(1) between "ath5k_hw_reg_write(ah, 0, AR5K_TIMER0);" and "ath5k_hw_reg_write(ah, next_beacon, AR5K_TIMER0);", "ath5k_hw_reg_write(ah, timer3, AR5K_TIMER3);" and "if (interval & AR5K_BEACON_RESET_TSF)","ath5k_hw_reg_write(ah, AR5K_ISR_BMISS, AR5K_PISR);" and "AR5K_REG_DISABLE_BITS(ah, AR5K_STA_ID1, AR5K_STA_ID1_PWR_SV);" in it tentatively and compile it againthen tried again, and then add "mdelay(10);" between "AR5K_QUEUE_DFS_LOCAL_IFS(queue));" and "AR5K_REG_ENABLE_BITS(ah, AR5K_QUEUE_MISC(queue),AR5K_QCU_MISC_DCU_EARLY);" in "ath5k_hw_reset_tx_queue()" in qcu.c .Finally the mesh-network is OK! I'm not sure what is exactly wrong with ath5k,is this a bug? or did I do something wrong?
