ok. i loaded the hwpmc - kldload hwpmc
and run pmcstat -TS inst_retired.any_p -w1

PMC: [inst_retired.any_p] Samples: 220 (100.0%) , 36 unresolved

%SAMP IMAGE      FUNCTION                       CALLERS
 67.4 kernel     acpi_cpu_idle_mwait            acpi_cpu_idle

it is a clean server and its doing nothing right now

why is so high % using  acpi_cpu_idle_mwait ?

ti have tried in bios various combinations of power management
maximum power, balanced, minimum etc... but with no luck

by the way - i even installed a clean bsdrp 1.97 - absolutely identical
situation with  acpi_cpu_idle_mwait using 70%
please could you help with this ?
