>Yes, ath.ko is compiled without CERTIFICATION_ONUS flag;
>(probably file compiled but always return NULL during pattern detector init).

Thanks, my mistake cause I replace the folder ath in backports with the one from master branch and I didn't change all of CONFIG_... to CPTCFG, now I got:

ath: country maps to regdmn code: 0x37                                          
ath: Country alpha2 being used: FR

ath10k: dfs region 0x0

And another different backtrace than before:

My station can see the wifi from ap but it can not connected to it yet. Could the backtrace 
say anything about my problem?
