TL-WR1043ND v1 ar71xx on HT40 the wifi crashes

Description

I use a TP-Link TL-WR1043N/ND v1 Barrier Breaker r40528 / LuCI (svn-r9964) and a TL-WA850RE v1 Barrier Breaker r40528 both HT 40 below on channel 11 enabled with Force 40MHz mode.

The WR1043N is in mode AP WDS and the WA850RE in Client WDS.

iperf -n 20000M let crash the wifi after 5 to 10 min. The SSID is visible but no connection are possible and no wifi client is reachable. Restarting the wifi on the AP enables the wifi again. In AP Mode HT20 there are no problems.
