The thing is that as I had to compile many times my kerne= l in order to try many .config, I had time to try to run ./latency when com= pilation is made. And there is no problem with latencies for example.
What does make exactly the load generator ? How can I try to debug it ? <= br>

Unfortunately, latencies obtained without lo= ading the system are
meaningless. So, generating a load is mandatory. I = am afraid you will
have to debug why the load generator does not work fo= r you.
