    Bugged C-States(C3/C6) on new uCode(0x3C) for Haswell-E.


      Dear Intel.

      When I test stock capabilities my CPU Core i7 5820K (Turbo Boost behavior) with last public available uCodes for Windows my system after some time idle freeze aka MWAIT bug on Skylake-S.

      After hard reset my system motherboard report POST :00(no CPU equal no PLL ) .

      And after second hard reset my system boot normally, I  instantly deactivate C3/C6 States(aka disable core parking) .

      When will be released fixed uCodes for this issue(C3/C6 State bug) for Haswell-E?

      Best regards .
