Bug description:
  [Impact]
   * System hang up when run Prime95 10~15 minutes
  [Test Plan]
  1. Find a unit with i9-12900k CPU and liquid cooling
  2. Connect to Internet and install below tools
  >sudo apt update
  >sudo apt install stress-ng
  >sudo apt install s-tui
  >sudo systemctl stop thermald
  >sudo thermald --no-daemon --loglevel=debug --adaptive --ignore-cpuid-check > thermald_log.txt &
  download prime95 linux version: p95v308b15.linux64.tar.gz and decompress
  4. Stress test: (you may need to open multiple terminals for the test)
  >./mprime #decompressed from p95*.tar.gz
  >sudo stress-ng -a 0 --class cpu,cpu-cache --ignite-cpu -v
  5. monitor cpu temperature for 6 hours if you didn’t hit overheat and shutdown issue.
  >sudo s-tui -c

  [Where problems could occur]
   * it install Passive Policy as default and use PL1 max/min from PPCC, there may be some edge cases that don't handle well.
