Hi Ben,

Tried it but still have the recurrent stack trace warning we had after the
last compat-wireless update. 
This was the most "visible" regression we were experiencing we the updated
ath10k drivers. Which other problems are you addressing?

I'm not exactly sure, but it seems that the trace is now a little less
frequent.

This is an extract of the console log (from Linksys EA8500 router):
