Good morning everyone!
I'm having an issue with a 2951 ISR upon which I'm trying to load the IOS for CME 9.5. I had no issues loading the IOS on to the device but it consistantly fails on boot. Here is what I see on the console during the boot process
System Bootstrap, Version 15.0(1r)M6, RELEASE SOFTWARE (fc1)

In looking at this, it seems as though the IOS image checks out. I erased and readded a couple of times to make sure the image wasn't corrupt, this image was pulled off of another 2951 router that is currently running it without issues.
I have also double checked the hardware in the device and there are not currently any add-in cards that could account for this error.
Any thought?

Faulty router, contact TAC for replacement.

Other IOS versions work just fine though. I can run both:
c2951-universalk9-mz.SPA.152-3.T3.bin (CME 9.0)
c2951-universalk9-mz.SPA.151-4.M4.bin (CME 8.6)
What leads you to believe the hardware itself is faulty?

That is really for the TAC to clarify.

OH OK just your best guess then. I thought I was missing something obvious and was curious what it was

You can try updating rommon. But that's pretty much all you can do about something that has no evident explanation.
