Description

On ASUS M5A97 EVO R2.0 with ITE IT8721F and AMD FX-8320E, LHM 0.9.4 detects CPU and cpu-related sensors correctly.
After upgrading to nightly 0.9.5 (pre551+f6c2c70a509a882449990e2d91afd0b24a8b9a00), CPU is not created — only motherboard (ITE IT8721F) and GPU are shown.

Steps to reproduce:

  1. Run 0.9.4 -> CPU detected
  2. Run 0.9.5 (nightly) -> CPU not detected

System info:

  • Motherboard: ASUS M5A97 EVO R2.0
  • SuperIO: ITE IT8721F
  • CPU: AMD FX-8320E (Family 15h)
  • OS: Windows 11 Ent

Research direction

Reproduce the regression on the ASUS M5A97 EVO R2.0 by comparing LHM 0.9.4 with nightly 0.9.5 (pre551+f6c2c70a509a882449990e2d91afd0b24a8b9a00). Trace the CPU-detection path for the AMD FX-8320E Family 15h. Done means the CPU and its related sensors appear in 0.9.5 as they do in 0.9.4.
