ntpd drifts depsite pll state


I have a strange problem with ntpd: clock drifts while the daemon
reports kernel status pll, which as I understand means NTP
synchronisation is good:

# cat /etc/ntp.conf
pidfile         /var/run/
driftfile       /var/db/ntp.drift
logconfig       -syncstatus

# ntpq
ntpq> kerninfo
associd=0 status=c016 leap_alarm, sync_unspec, 1 event, restart,
pll offset:            0
pll frequency:         0
maximum error:         756.265
estimated error:       1.6e-05
kernel status:         pll
pll time constant:     3

pps frequency:         0
pps stability:         0
pps jitter:            0
calibration interval   0
calibration cycles:    0
jitter exceeded:       0
stability exceeded:    0
calibration errors:    0

# ntpdate -uq
server, stratum 2, offset -10.022205, delay 0.02600
 2 Feb 03:42:25 ntpdate[15369]: step time server offset
-10.022205 sec

Is there something wrong in the configuration, or do I misunderstand
kerninfo output?
