I mentioned this in another thread, but I now have better information
and thought it appropriate to create a thread just for this issue.
My kernel is as follows.
# uname -r
4.11.0-rc3-wt-ath+
I've built this directly from the sources at hash 4af3c7bf12da and
upgraded a vanilla Debian stretch RC2 install. Note that I've tried
several kernels and this problem seems to be present in all of them.
My card presents as follows.
# lspci -v
02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless
Network Adapter (rev 32)
Subsystem: AzureWave QCA6174 802.11ac Wireless Network Adapter

My hostapd version and config file are as follows.

When trying to host an 5GHz AP using ACS, the first attempt after
inserting the drivers into the kernel always fails. See the verbose
logs below.
