--- Comment #1 from Greg V <greg at unrelenting.technology> ---
On my Ryzen system, r352684 (or something.. but nothing else TSC related
happened recently) caused the TSC to go completely nuts, time is quickly
becoming off by many minutes, I looked at the clock yesterday and it was 3
hours behind :D

kern.timecounter.hardware=HPET seems to be better (-14 sec desync from NTP in
an hour without an NTP daemon, that's not crazy and should be manageable by
NTP)
