Hi, Chrony at armv7l, a Beaglebone running Debian 8.1 (linux 4.1.5) looks to be broken.
I have tested both a Beaglebone white and a Beaglebone black. I have tested with the Debian package (1.30), 2.1.1, and git HEAD. So, usually Chrony does sync the clock, but gives weird frequency estimates. Since this devices don't have a RTC, I have tried to start chrony both with a time way in the past, but also with a "correct" time already set.
