Wrong. CPU load is very more high than 4%. Only /proc/loadavg report the
right load of the CPU because the ppa_engine() is interrupt timer driven
and is not checked by usual user level programs such us ps or top (or
time). Maybe with the old driver in 2.0.33 this will not happen because
ppa was tq_scheduler and not tq_timer driven but I am not sure of this.
