https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256781 --- Comment #18 from Colin Percival <cperciva@FreeBSD.org> --- Thanks for all the details. After some investigation, it looks like there'= s a specific issue with TSC on T3/T3A instances which affects the clock calibration. In the long term we should switch over to using the KVM pvclock (which won't have this problem) but that code isn't in the tree yet; for 13.0 I don't th= ink there's any good solution. --=20 You are receiving this mail because: You are the assignee for the bug.=
