Hi

I am using an Atheros AR928X Wireless Network card on Fedora Core 16 
via hostapd so that I can use it as an access point.  I have had the 
same problem and I think it is documented as an outstanding problem on 
the compat-wireless page but wanted to confirm that and / or perhaps 
find out what is happening if anything with it.  Or its completely 
something I am doing wrong [ MOST LIKELY ]

I have upgraded from Fedora 14 to 16 and now installed via source 
compact-wireless-next software and still have the same problem.

The errors I see are as follows...

Dec 28 19:55:37 sun kernel: [424600.248087] ath: Failed to stop TX DMA, 
queues=0x008!

Dec 28 19:55:38 sun kernel: [424601.360311] ath: Could not stop RX, we

and on and on...

This is always re-creatable by using speedtest.org and testing the 
speed of the connection.

Any one have any ideas please?

Thanks

Paul
