This may be a stretch, but check  the output of `show c7200` for the
hardware revision. We've run into some buggy NPE-400 hardware that
showed a hardware revison of  either 1.0 or 1.1 that required
replacement. In our case the bug revealed its self when it had max ram
(512mb) and some portion above 256 was accessed.
