No, Heiko is right here. If one of the "CPU_DOWN_PREPARE" fails then the following CPU_DOWN_FAILED will be invoked on the correct CPU. However if we are further down the road and the final ARCH specific "die" failed (just before CPU_DYING) are invoked then we get this done on the wrong CPU. > Thanks, > Richard Sebastian
