Kernel Panics when limiting number of cores

Issue

• We would like to disable the hyperthreading and limit the number of cores per CPU due to software licensing reasons. We are achieving this by making the change at the hardware level through the system BIOS.
  Unfortunately, after we make the change, the OS panics.
