I noticed that when updating from ntpd 4.2.7p97 to ntpd 4.2.7p206, I
noticed that the newer
version is sending some RS-232 data to the GPS soon after the PPS signal
has
started. I filed a bug report about this:

I don't know whether it's related to your issue, though, as I'm seeing
this on Windows.
Cheers,
David
