Hi all again, seems i hit another bug, my test setup is a three mesh nodes,
all in one room, two is alix pc engines with EMP9605H (ar9220) with antennas
like on soho routers and one is my laptop with dbii f52n-pro ar9220 based too.
Use compat-wireless-3.5-rc5-1-snpc on all nodes.
All three nodes work fine, but then i remove antenas from one of the node (it
contiue work only with pigtails) signal levels with this node is low but enough
to work, it continue to work but i have errors in dmesg on all three nodes:
ath: phy0: Failed to stop TX DMA, queues=0x001!
Links is become unstable, packet loss regardless to which node taffic is goes,
to node without antennas or betwen nodes with antennas.
I tryin change wireless cards with no results, but all what i try is ar9220 based,
just different manufactures. Also i try add ubiquiti nanostation M2 with openwrt
on it in this setup, and get same results on it too - dma erros and unstable links
with packetloss.
Then i connect antennas back, all strat working fine again withous erorors.
I think it seems low signal and/or low quality links is triggering with bug.
I also trying use stock kernel 3.2.x and 3.4.x, compat-wireless bleeding edge, but
no luck - same results.
Please give any suggestions how i can help find a root case of this bug to resolve
it?

also update - i also try to test it with AP<->client mode, just start hostapd
on one node, remove antennas nad start iperf, in this case there is no errors
and link seems very more stable then i use mesh nodes, may be this is also
802.11s related too.
