Subject: [ath9k-devel] How to solve the problem of "Failed to stop TX DMA"
Date: Wed, 22 Jan 2014 08:51:58 +0000	[thread overview]
Message-ID: <DD8BBA008051D14BB5B3843EC07BACF516C33D02@MBX3.wgti.net> (raw)
In-Reply-To: <21215.33088.277915.751120@gargle.gargle.HOWL>

On powerpc. 

Reproduce rarely, but always can see.

My step is that,
a). Running hostapd, stop it, and start wpa_supplicant, 
b). call SIOCSIWSCAN via ioctl to scan and call SIOCGIWSCAN to get scanning result.
c). stop wpa_supplicant and restart hostapd.

Thanks,
-Joe

Is this issue consistently reproducible in your setup ? What board/platform ?
