I'm thinking there were two jumps in the first little bit.  Maybe 60
seconds?

First ntpd decided to listen to my bad PPS, which was similar to
the system time.  Then it saw a cluster of servers that disagreed, and
crashes.

Do you have a GPS clock that is prefer?  Did you set the time to 2134,
restart gpsd so it is in the wrong epoch?  Then start ntpd?  very
repeatable for me.  Even on diffeeent NTPsc versions.

    bootstrap
    rm -R build
    mkdir build
    cd build
    ../configure
    make && make install

Same as always.
