=46WIW, it can reproduce this on two machines (one 4.9-RELEASE, one 5.1-REL=
EASE)=20
which both run ntpd. Takes some 10 minutes on both before the first steps=20
backwards turn up.

Unfortunately, both machines aren't very good datapoints because both have=
=20
pretty customized kernels and have -Os and -march optimized worlds/kernels.=
=2E.

Both have kern.timecounter.hardware: ACPI-fast, too.
