I though that machdep.hyperthreading_allowed had to be set to 1 to turn on hyperthreading ? I have a dual processor HP blade, and when I boot it up with an SMP kernel I get 4 CPU's. Setting that flag does not have any effect!
Any thoughts ? I dont think I have two CPU's each with dual core and without hyperthreading somehow! (though the thought did cross my mind...)
