Source is available under /usr/src/linux --> /usr/src/linux-4.8-rc5
System.map is available there, also as System.map-4.8-rc5.
System.map and System.map-4.8-rc5 is also available in /boot.
But the call trace still shows no symbols.
>From reading I understood that symbols from modules will not be available in
System.map. So what else should I do?
