In an almost similar case, we noticed high CPU usage when 
re-inserting a compact flash drive (back) into an NPE-G1/G2 
running SRC code, to the extent that BFD complained and 
brought down IS-IS on at least one of the network-facing 
ports.

We chalked it down to the router re-initializing the compact 
flash drive when it's re-inserted, eating up tons of CPU and 
causing a couple of "ripples" with some of the software 
processes.

It's been a while since we had to physically move the drives 
from/into the router, and I'm not sure whether any other 
customers have addressed this issue with Cisco, but we've 
moved a couple of SRC revisions ahead, and don't know 
whether it's still a problem.

Cheers,

Mark.
