Jorge and Brian,

Thanks for your input and ppa. Much appreciated. My reading of the
kernel LKML discussion is that something rather serious was screwed up
in the implementation of the nohz part of the  kernel scheduler and that
the patch was a first test of this idea. The results there and in this
bug thread seem to confirm that suspicion but I would be more
comfortable if the two kernel developers in that thread (Peter Zijlstra
and Arjan Van de Ven) had further responded on the issue. Perhaps a
Ubuntu kernel developer should engage with these devs on LKML to clear
this issue up...
