Dear all, I'm working on the wireless AP issue with ath9k driver now. I always can see the following error log, and the wireless will stop broadcast or client cannot connect to AP.
[212767.228324] ath: phy0: Failed to stop TX DMA, queues=0x004! [213045.584267] ath: phy0: Failed to stop TX DMA, queues=0x004! [213102.806419] ath: phy0: Failed to stop TX DMA, queues=0x005! [213121.954144] ath: phy0: Failed to stop TX DMA, queues=0x001! [213215.547168] ath: phy0: Failed to stop TX DMA, queues=0x001! Previously, I used the old driver v3.6.8 (stable branch). But even I update driver to the latest version v3.13, it still cannot solve the problem. Below is some info from my device: ieee80211 phy0: Atheros AR9300 Rev:3 Linux version 3.0.34 Loading modules backported from Linux version v3.13-rc8-0-g7e22e91 Backport generated by backports.git v3.13-rc8-1-0-gae71bd3 Would you please give some suggestions with your rich experience? Much appreciate your help! Thanks, -Joe
