Details - I setup my EA8500 with the latest LEDE branch. Configured some wifi networks, some OpenVPN connections, SQM, DDNS, UPNP and MWNA3.

After few seconds from the reboot (but yesterday it lasted 12 hours) the router crashes. Everything doesn't work. I can't ping it from the lan, from the wan, from the wifi. If I connect to the router lan directly and examine packets with Wiresharks it "seems" the router is doing something because I see packets originating from it (or at least from its mac address).

I tried to collect the log, but really I don't know how I should do it to be helpful. This is what I collected and it seems compatible with the crash time.

One or more files have been attached.
