I face very similar problem, but I have v2.1 hardware of QCA6174 (I assume you do not have QCA6147 neither). I installed Kubuntu Bionic Beaver (18.04) from fresh.
I still face the firmware crash IF (and only if) I switch off / hibernate my laptop with active WIFI connection. If I switch off wifi before hibernate, everything is perfect.
