One is the actual ntpd itself, the other is a DNS resolver
process which is started by the former.

That's a different problem.

Don't set maxpoll unless you know for sure what it does, why you
want it, what the possible risks are, etc.... Your machine may need
a lower maxpoll in order to detect and deal with your clock drift,
and if you force it this high, you may not be able to keep good time.

Without more information, it's hard to say. What are your HZ
settings? Have you enabled or disabled APIC or ACPI? There's a
whole host of other potential issues.
You could try the latest dev snapshot, but it may or may not make
much of a difference for you.
