Recently I have been seeing a problem on multiple devices where pppd never completes. It
looks like the ISP thinks that pppd is ready for IPCP, but pppd isn't and so discards
the IPCP packet (discarding proto 0x8021 in phase 5) and things just go around in a loop
like this forever until the connection is interrupted and it starts again.
On starting again, it will either connect normally, or will get itself into the same loop
and never progress.
Has anyone seen that before? It seems to be a recent thing - I've only seen it in the
last few months.

I haven't used pppd for a while and these are the obvious questions:
The latest pppd appears to be version 2.4.7, so I would suggest testing with
that version if yours is older. Debian Stable, for example, is still on 2.4.6.
If that doesn't help, I suppose it's time for a bug report.
Have there been relevant upgrades at your end or is this most likely an ISP
equipment change? If you think you have a chance of contacting Level 2 (or
whatever they call it) support at the ISP, it's probably worth trying, as they
may be able to report it to their vendor.
I know this is totally obvious... I assume it's the same ISP in all cases.

I don't know if I had that specific problem, but some time back I had my
PPPoX setup break.
Yeah, it was wierd but it worked well for a year or two, then poof...
I had a Draytek Vigor120 acting as a pure adsl modem passing through to
a Linksys EA3500 router which did the ppp stuff. Suddenly stopped doing
the ppp stuff, no firmware changes made. Replacing the Draytek with
another unit gave the same result.
There was no error message and buggerall diagnostics I could do, but
your problem sounds like a possibility.
Internode?
I ended up making the Draytek do the ppp stuff as well.
