Could anyone please explain me why I have this infinite cycling message:

Nested r4k_return_to_monitor call (442 times)

-Traceback= 0 60338694

Nested r4k_return_to_monitor call (443 times)

-Traceback= 0 60338694

I have these infinite cycling messages during boot-up on 7206VXR chassis with installed C7200-I/O-FE module and NPE-400 module.

I have no problem running 7206VXR chassis with installed C7200-I/O-FE module and NPE-150 module:

Have you tried with a software from 12.1T train?
