The router stays up for a minute or so and then restarts. This has been going on for about and hour and it's happened before.
I've contacted support with syslogs and sys ver dbg ouput.
I don't think the sys ver dbg output (below) relates to the current problem.
I've tried switching power supplies. Is there anything else I can try to get it going again?
