Ath10k Firmware crashes on QCA9888 board

Ath10k Firmware crashes on QCA9888 board

[Joan Josep]

Hello everybody

We bought some 11AC cards and we experienced some issues.

We are using a qca9888 chipset 11AC mini pci card on a 4.9.0 kernel 
compiled for an ARM processor (imx6) using Ubuntu 14.04 as operating system.

We are experiencing some problems when we try to load the ath10k_pci 
kernel module to use this card.

This is the resulting dmesg:

--> $ modprobe ath10k_pci
