I've seen some references to above problem, but no clear answer. The
'ntpd' is complaining a lot...

I have ASUS P4S800. Here is some extracts from dmesg (I can provide
more complete dump, if anyone wants something specific.)

Losing too many ticks!
TSC cannot be used as a timesource. (Are you running with SpeedStep?)
Falling back to a sane timesource.
