I have a test lab with two 7206VXR routers which I've been using for several months now. One of the routers is behaving oddly; if I issue a reset command from enable, it will reset, but then hang, failing to load IOS and not responding to the break key. If I power cycle the router, I get the same thing. However, if I press the recessed CPU reset button on the front, the router reports the CPU reset and boots up normally.
I thought this might be a confreg setting, but I set it to 0x2102, and I get the same issue.
As I said, this router used to not do this; it just started doing it recently. I've not changed the IOS, and my second 7206XVR, which is identical, does not exhibit this behavior.
Does anyone know what might be causing this? It's more of an annoyance than a problem, but I sure don't want to run into this on the CCIE Lab and not have a solution. Thanks.
