I have the same problem after the switch to 6.0 from 5.4 :

http://lists.freebsd.org/pipermail/freebsd-stable/2005-November/019171.html

I've set the kern.timecounter sysctl to i8254 as suggested by Joseph Koshy.
Now it seems that i get these messages rarely, maybe onece a day.
Before this i get maybe 4-5 daily.
Now it clearly looks that this has something to do with excessive thread
usage.
