Congrats +1.

Sasha, it might be helpful to see this_load is from:
this_load1: this_load = target_load(this_cpu, idx);
or
this_load2: this_load += effective_load(tg, this_cpu, -weight, -weight);
It really does not seem to be this_load1, while the calc of effective_load is a bit complicated to see what the problem is.
