Acpi Genuineintel---intel64-family-6-model-58 May 2026
The identifier GenuineIntel Family 6 Model 58 refers specifically to the Intel Ivy Bridge microarchitecture (3rd Generation Core). If you are seeing this in a system log followed by an ACPI (Advanced Configuration and Power Interface) error, it typically indicates a communication mismatch between the CPU's power/thermal management and the motherboard firmware. 1. Hardware Identification
The kernel uses this to apply vendor-specific errata, feature detection, and power management policies. When you see genuineintel (often lowercased in logs), it means the system has positively identified an Intel CPU. acpi genuineintel---intel64-family-6-model-58
The ACPI table is stored in your BIOS. If the BIOS is outdated, it may struggle to communicate the processor's power states (C-states) to a modern operating system like Windows 10 or 11. The identifier GenuineIntel Family 6 Model 58 refers
4. Debugging ACPI on Ivy Bridge (Model 58)
If you see ACPI errors with this CPU, common issues: Cause: BIOS _CST includes C3/C7 but missing MWAIT hint
Action: Try resetting BIOS to "Default Settings" or disabling "Fast Boot" in Windows.
Part 4: Why Does ACPI Care About CPU Model?
ACPI needs to know the precise CPU model for several reasons:
- Cause: BIOS _CST includes C3/C7 but missing MWAIT hint.
- Fix: Update BIOS or patch DSDT to use native MWAIT via
intel_idle.max_cstate=6kernel param.
Understanding the ACPI GenuineIntel-Intel64 Family 6 Model 58 identifier is essential for troubleshooting system stability, optimizing performance, and managing driver updates. While it looks like a cryptic string of code, it provides a specific roadmap to your computer’s "brain." 🔍 What is Family 6 Model 58?
