hi

I am trying to setup a new device

It works ok, but as soon as I add the ath9k driver in my compilation, I get this

Any idea ?

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
grafik
Remember to redact passwords, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

it does not look like a release kernel.

Look similar

Can' t do that as the kernel crashes at boot, even after a full reset (not keeping config files)
