[c-nsp] Problem connecting DSL with 12.3(11)T3

I am having problems with a Bellsouth DSL config under 12.3(11)T3, I 
believe it may be an IOS issue.  When I reload the router it connects, 
I get my IP, but then it shortly disconnects, and it will not 
reconnect.  I flap both the e0 and dialer1 interfaces, but nothing.  No 
matter what I try to clear using "clear pppoe", this always remains:

nco#show pppoe session
      1 client session

Uniq ID  PPPoE  RemMAC          Port                    VT  VA         
State
            SID  LocMAC                                      VA-st
     N/A   4007  0003.4272.c002  Et0                    Di1  Vi1        
N/A
                 0004.dc0c.ead9                              DOWN


Yet Dialer1 no longer shows an IP address set:

nco#show ip int dialer1
Dialer1 is up, line protocol is up
   Internet address will be negotiated using IPCP
   Broadcast address is 255.255.255.255
   MTU is 1492 bytes
   Helper address is not set
   Directed broadcast forwarding is disabled
   Outgoing access list is not set
   Inbound  access list is not set


debug ppp auth and neg just repeatedly shows:

Its strange that I can reload the router, and it will come up, but once 
the connection has dropped, I have not been successful in revising it.
Anyone have luck with 12.3(11)T3 and DSL/PPPoE?  See anything in the 
config below that may be questionable?
