Fwd: ath9 wireless problem on ar9220 and ITS-G5

Hello,

I'm Francesco Vigolo,

we have a project with some WiFi cards using ar9220 chipset (minipci). 
We have implemented these cards into a Linux embedded system. We are 
using Openwrt linux 4.4.0 Kernel and ath9k driver (backports-20151218). 
We are implementing an ITS-G5 system. Seems that cards are not working 
correctly higher than 8595 MHz (ch 179), while 5895 and lower channels 
are working. If I set 5900 (180) or 5905 (181) or another ch like 5915 
(183) MHz the driver stop working. We have patched drivers to allow 
these channels from the perspective of regulatory and to allow this band 
(commonn-init.c, hw.h, regd.c, db.txt). Could you please indicate us a 
linux driver version working for sure with ar9220 chipset @ higher freq 
than 5895? Hardware for sure is working. In attachment a log indicating 
the problem with the driver.Let me know if you need more informations.

Here *iw reg get *and *iw list *showing that regulatory has been patched 
correctly...
