It's fine to disable the additional cores/cpus on a dedicated NTP machine, but I wonder if there is a solution that allows both the TSC and all the cores to be used at the same time. Is it even possible to completely sync the counters across CPUs (not just get close)?
You could try pinning ntpd to a single CPU using the "taskset" command. It wouldn't give all the applications the benefit of a perfectly synchronized clock, but if you just want ntpd to be happy then it ought to work as well as turning SMP off.
