Hi there,
it's been a while, but I have good news: tried Kernel 4.2.3 from
Fedora and it just works! No need to use irq_mode=1 (and I also
removed skip_opt), tested with firmware API 5 from ath10k-firmware
since a couple of days now. No issue so far.
Thank you for the help and the work, and sorry for not being very
useful in investigating this eheheh.
Cheers!
Enrico
