tsc_freq, 1)' change the last parameter to '0' and see if they go away.


I still get calcru messages too. And I have noticed that I get these
messages when I run ps or top command. When we run ps,
fill_kinfo_proc_only() is called, and I think calcru() and calccru()
for kthreads are called in that function.

Ok, that makes sense (as to why calcru() is getting invoked). I would try the
change I suggested earlier of forcing the tsc to be treated as statically
scaled rather than dynamic.
