No indeed I don't have this acpi_cpu_idle_mwait function on the top:

PMC: [inst_retired.any_p] Samples: 156 (100.0%) , 44 unresolved

%SAMP IMAGE      FUNCTION                       CALLERS
 32.1 kernel     cpu_search_highest             cpu_search_highest:28.6
sched_switch:2.7 sched_idletd:0.9
  4.5 kernel     cpu_search_lowest              cpu_search_lowest:3.6
sched_pickcpu:0.9
  2.7 libncurses start_color_sp                 wbkgrnd
  1.8 kernel     sched_switch                   mi_switch

Did you customize your performance_cx_lowest rc.conf ?

Olivier
