I agree that staying with 12.2 is the safest choice, but I was eager to 
jump to 12.3 since we have many routers already running 12.3 (without 
this problem), and also because that we might be doing IPv6 stuff 
sometime soon.

The features that we using on this box are basically terminating a 
couple of channelized E1s, using HDLC, and we are running ISIS as our 
routing protocol with a few ACLs and route-maps here and there. Nothing 
complicated. (*No* IPv6, VPDN, BGP, IPSEC, MPLS, policy-routes, or 
anything fancy on the router.)
