Hi all
My router again has started to randomly reboot , really cant put my finger on what is causing it, very very random. I did have this same issue a couple of months ago or so and ended up flashing the router and then setting everything back up.
This time i have set the router to send the logs to Splunk so had a look as these are the last logs i am seeing before a gap ( reboot )

I have attached a .txt with about a minute or so of the kernel logs just before the panic.

Anyone have any ideas on how to fix ?
