So I moved the warning to select_idle_routine() and made it called after detect_ht(). It also needs Andi's patch for 32-bit. i386: Move MWAIT idle check to generic CPU http://lkml.org/lkml/2008/1/2/358 [PATCH 1/2] x86: move warning message of polling idle and HT enabled [PATCH 2/2] x86_64: move select_idle_routine() call after detect_ht() Thanks, Hiroshi Shimamoto
