Yes, it helps. But according to CC_CDG(4): smoothing_factor - Number of samples
used for moving average smoothing (0 means no smoothing).  Default is 8.

That's why I tried to set 0. If smoothing_factor=0 is abnormal setting for this
tunable, documentation needs to be changed and restrict possibility to set
smoothing_factor to 0. In any case, it's not normal behaviour when OS freezes
and restarts, IMHO.
