The thing is that as I had to compile many times my kernel in order to try many .config, I had time to try to run ./latency when compilation 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 ?

Unfortunately, latencies obtained without loading 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 for you.
