Subject: ath: phy0: Failed to stop TX DMA

Hello!
The following messages appear in my console approx. once in a minute.
Please, help me to fix that.

I use "Atheros Communications Inc. AR5008 Wireless Network Adapter
(rev 01)" PCI card on linux-3.8.8 x86_64.
The connection to WPA access point works, although SSH freezes
periodically for a couple of seconds.

The first message comes from net/wireless/reg.c
, the second from drivers/net/wireless/ath/ath9k/xmit.c and is output
via ath_err().
Looks like something is wrong with my system. I need assistance to resolve it.
