That looks much healthier though it doesn't explain why your system
clock is ~2500ppm out to start with.  You may get one further small
(~128msec) time step as part of ntpd's PLL calibration.

Over time (probably a couple of days from scratch), the "poll" rate
should increase to 1024.  If it doesn't, it may indicate that your
system clock stability isn't very good or you have excessive jitter
in your reference.
