firmware crash dmesg log

device: Qualcomm Atheros QCA6164
Kernel modules: ath10k_pci
Firmware: linux-firmware 20161005.9c71af9-1
NetworkManager: networkmanager 1.4.2-1

Disconnect the wifi will had a firmware crash and then can't scan any wifi connection. After that I must be restart NetworkManager to make it work again. 

I found that when I didn't connect any wifi, mac address will change to other address, restart NetworkManager mac address will change to anther again. When I had a connection mac will change to the right one.

And other problem, sometime scan wifi very slow.

Here the "dmesg -w" log in attachment
