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

Stuff that looks weird to me:
> interface Ethernet0
> half-duplex
Really?
Also:
> nco#show ip int dialer1
> Dialer1 is up, line protocol is up
Shouldn't it be up/up spoofing? This doesn't really matter, but I was
just curious if the code is different now.
So here is the deal:
> *Mar 8 01:04:02.975: Vi1 LCP: O CONFREQ [REQsent] id 2 len 10
> *Mar 8 01:04:02.975: Vi1 LCP: MagicNumber 0x04F29287
> (0x050604F29287)
> *Mar 8 01:04:04.991: Vi1 LCP: TIMEout: State REQsent
You send an (O)utgoing CONFREQ and it never gets ACKd by the PPPpeer.
So something is getting "stuck" after the connection drops.
Can you also turn on "debug ppp packet"? Wonder if you are getting
encap failed or something. I might shutdown the fa0 interface, and do a
debug ip packet as well to watch the packets going out the eth0
interface. Also, look at "sh int" and see if anything is weird on the
lan interfaces.
Kinda sounds like a bug but not enough info to say for sure.
