I think the box is telling you what the problem is:

Wonky RAM. I suggest pulling the memory and reseating it. If that
doesn't help, replace it.

Regards,

Marco.

Either bad RAM or a bad motherboard with a bad memory controller.
Sounds like an RMA situation either way. Reseat the RAM (although that
type of failure doesn't sound like it would help), or RMA both through TAC.

I haven't seen IOS fail in such a way like this.

I've had a chassis fail in this exact way a few times. Doing a total
hardware swap with the same exact IOS version, and same exact config
made it not fail that way ever again.

So, I'd imagine you have a bad motherboard (ie. chassis) on this
router that needs a fixin.

Clearly suspecting the RAM is a good place to start however
it could be a random bug or hardware failure calling the "Bad
RAM report" code with the mentioned parameters. It is in fact
VERY suspicious, to me, that the location and written value are
the same.

Does your platform even have RAM at that address?

Perhaps it's time to ARM the RMA.
