I watched again the patch I committed to STABLE_8 and I can't find anything wrong with it. Also the fact that the setting machdep.lapic_all=3D1 fixes this means that this may be an atrtc working problem. Maybe new atom machine expose a problem with it? I'm thinking if we might switch this into an opt-in rather than an opt-out feature. Attilio --=20 Peace can only be achieved by understanding - A. Einstein
