ath: phy0: Failed to stop TX DMA, queues=0x004!
ath: phy0: unsupported hw bitrate detected 0x15 using 1 Mbit (<- happens
with AR9132)
My experience with:
AA r39154
hostapd r39155
mac80211 r39150
And it seems to happen mostly with Atheros AR9130 rev 2 while with Atheros
AR9132 rev 2 and AR7240 rev 2 it is almost nonexistent.
