I've had reports of this in the past. The other end is sending a
``code 5'' packet - something that doesn't appear in the spec :(
ppp(8) just ignores these (emitting a warning), they shouldn't be
causing any problems themselves (even if CBCP is actually being used).
Try enabling IPCP logging. You may be having a problem at that
level, or alternatively, perhaps the peer thinks you've already got a
connection and is (rudely) dropping the connection because of that.
