Subject: [ath9k-devel] How to solve the problem of "Failed to stop TX DMA"
Date: Wed, 22 Jan 2014 08:04:22 +0000 [thread overview]
Message-ID: <DD8BBA008051D14BB5B3843EC07BACF516C33C2D@MBX3.wgti.net> (raw)
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
