This is a shot in the dark but try configuring "no ip icmp redirect".
Especially if you use this router to route packets between VLANs on
the same physical interface. IMO it's a bug that this isn't there by
default (and I think this was changed somewhere down the line).
Otherwise, try the "debug packet capture"-on-linecard trick to see
what traffic is hitting the LC CPU.
