I still have the same problem, using pppd built from August 2nd (+/- one
day) sources, and I am not using PAP - my ISP uses simple password
authentication.  Unfortuantely, they also have a 30-minute or so idle
timeout, so they will drop my connection occassionally.  pppd is set up to
persist, and usually it does, but after several (exact number not known)
disconnect/reconnect cycles, it will fail.  In those cases, it seems to
keep trying, but never establishes a viable connection;  it appears that
the LCP Hello's don't get responded to.  The only solution in this case is
to stop and restart pppd.

So, Yes, it still happens, and it doesn't require PAP to make it happen.
