Since it works everywhere and you are the only one able to reproduce the
problem, you are the only one who can debug it.

Look at sys/net/if_spppsubr.c and search for the sppp_keepalive function.
This is called every 10 seconds and checks all interfaces. Add a few printfs
there and find out why it does not hit the
