https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D216759 deJong <hellrider8881@yahoo.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hellrider8881@yahoo.com --- Comment #15 from deJong <hellrider8881@yahoo.com> --- I managed to find a patch which adds KVMCLOCK support, however it's pretty = old and I did not get around testing it. I believe it has not been implemented in the -CURRENT branch yet. Also, I read here: http://markmail.org/message/pjtay3dghuqpv4hg that using TSC-low is not entirely foolproof (whatever that may mean, I am = more of a sysadmin) so there are probably some issues with using it. Mailing list: https://lists.freebsd.org/pipermail/freebsd-arch/2015-January/016587.html Patch: https://reviews.freebsd.org/D1435#inline-51273 Maybe somebody could take a look at it and test it to see if it resolves th= is issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
