I tested this with my 2.6.22-rc3 kernel, here are the results: without any special boot parameters: problem does appear highres=off nohz=off: problem does not appear highres=off: problem does not appear nohz=off: problem does appear I additionally built my 2.6.22-rc2-mm1 kernel without High Resolution Timer, but the high ping problem is still there.
