[c-nsp] 7206vxr reloading with software forced crash?

Thanks for all the responses off-list (and on-list too) that I've
received. I've already opened a TAC with all the info, but still I'm
looking for extra advice :)

This is the actual config of the router, and the "show ver" output. Part
of the config is trimmed (for safety/personal reasons), so excuse me if
I have a mistake there.
