Hi Gilles,
you don't feel like to repeat.
I'm trying all the things that you told me and i will do all the missing
test that you told me.
And now this is the result of latency that i ran. It seems correct.
root@domain.hid# ./latency
== Sampling period: 1000 us
== Test mode: periodic user-mode task
== All results in microseconds
warming up...
