I do not see anything stranger. Only, using Linux Trace Toolkit with
modifications when there are few filters, I observe that of timer Bottom
follows IRQ 0. And when there are more filters, IRQ 0 takes place when
network Bottom Half is taking place, so the timer Bottom Half is delayed
the end of the network Bottom Half. Can it be related?
To measure kernel CPU I have used the trick of running another CPU with
priority. According to the time this second process is delayed an
%CPU is obtained.
I do not understand what is happening. Any help would be very useful.
