Hi,
I'm trying to use Coova-Chilli on this ar71xx based device which supports
both 2.5 and 5GHz respectively. I'm facing a problem in that when I start
Coova-Chilli, it crashes out and either locks up the device or kills some
processes due to being out of memory.
This only happens when I set Coova-Chilli to use the ath10k 5GHz wifi
network, not 2.4GHz or LAN port (it works fine on those). Haven't seen this
before on other devices that use the same ath10k driver / ar71xx chip.
Below is what is printed in the log when Coova-Chilli starts up. You can see
it goes a bit crazy and ends up killing other processes.

Any help/advice would be much appreciated. I have also tried using the
latest code from github as of this morning (I was a few weeks behind).
Thanks,
