What do you think if I set drift file to '0' value ?
Do you think this ntp
behaviour happens again ?
I'm able not to understand if my problem is hardware
clock frequency which ntp cannot deal !

That's kinda good that it doesn't change, and NTP is designed to handle
500PPM
of drift. That value was at least 2x the worst clock normally
seen.
So if you
can look at the tickadj program and calc_tickadj, you might be
able to adjust
the system clock to be moch more stable. Ideally the
drift value should be the
smallest possible positive number, and that's
what calc_tickadj tries to do.
