Upgrade of FreeBSD 10.1-RELEASE-p8 to FreeBSD 10.1-RELEASE-p16 resulted in pcbsd kernel: calcru: runtime went backwards from  usec to  usec for pid.

Notable effects on FreeBSD 10.1-RELEASE-p16 are slow clock and latency in system's responsiveness.

Using previous boot environment FreeBSD 10.1-RELEASE-p8 gives no such errors.

Please find attached log.

- Original report for now unsupported 10.1-RELEASE PC-BSD release.

- Log appears to indicate notifications after positive ntpd time skew/resets, approximately intended behaviour: reporting consequences of clock skew, unlike bug 232914 which reports overflow.

Our apologies for not addressing your report earlier.
