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:
