ath10k mit OpenWRT 18.06

[mail at adrianschmutzler.de]

Hallo,

 

ich habe ja bereits seit einiger Zeit Freifunk-FW mit OpenWRT 18.06 im
Einsatz. Das einzige verbliebene Problem ist der ath10k-Treiber, der im
dmesg fleißig Fehler ausspuckt:

Offensichtlich probiert der hier verschiedene Varianten durch und findet
erstmal nichts.

 

Das Ganze tritt auf allen meinen Geräten mit ath10k auf. Die 5 GHz
interfaces funktionieren aber scheinbar problemlos, lediglich der
Bootvorgang wird deutlich verlängert.

 

Hat jemand eine Idee, was man da machen kann/muss/sollte?

 

Grüße

 

Adrian
