[c-nsp] Ambiguous ACL "log" in 12.2(58)SE2?

Wow.  I think you can include precedence between the ports and the log.  Can
you put that in to maybe match all precedences?  Otherwise, I think I'd hold
off on this release, sounds like it needs a good deferral.

Nope, it's still ambiguous.

The "scary part" of this is that simply updating your IOS removes some of
your ACL lines (when startup-config is loaded they also error)
