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.
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.
