I have noticed similar time issues after upgrading from 8.2 to 8.3. I haven't
had time to investigate, but often the time drift "exceeds sanity limit."
So, the problem is present pre 9.x. I never had this problem when running 8.2.

Subject: time issues and some more
I resently upgraded a Dell PowerEdge R710, to 9.1-stable, we mainly use it as
a backup to several zfs servers (doing send|receive) without major issues till
the upgrade, it was running 8.2-stable.
now, we see that sometime the time drifts, and today I noticed that it was
hung, and once I got unto the ipmi console this is what i got:
[SOL Session operational. Use ~? for help]
swap_pager: indefinite wait buffer: bufobj: 0, blkno: 3864, size: 12288
and things started moving again,
in /var/log/messages:
Jan 16 03:27:35 store-02 kernel: swap_pager: indefinite wait buffer: bufobj:
0, blkno: 3864, size: 12288
but the REAL time is 7hs ahead!, so time stood still ?
and now, of course we get:
Jan 16 03:54:19 store-02 ntpd[38163]: time correction of 25216 seconds exceeds
sanity limit (1000); set clock manually to the correct UTC time.
I will now reboot, and try a newer kernel and check, but any insight will
be very helpful,
thanks,
danny
