Acpi Genuineintel---intel64-family-6-model-58

Linux kernel has excellent support:

However, Ivy Bridge lacks some newer power features like HWP (Hardware P-states) and C8/C9/C10 found in Skylake and later.

The string acpi genuineintel---intel64-family-6-model-58 is not a bug, not a warning, and certainly not a cause for alarm. It is a fingerprint – a piece of forensic evidence left by the Linux kernel to prove that the ACPI subsystem and the CPU driver have successfully identified and configured your Ivy Bridge server’s processor.

For the average user, ignore it. For the system tuner or kernel developer, it is a valuable breadcrumb. It reminds us that under every sleek user interface, a silent conversation happens between firmware and kernel – one that speaks in families, models, and ACPI states.

So the next time you run dmesg | grep genuineintel, smile. You are looking at the digital handshake that keeps your server running efficiently, core by core, C-state by C-state.

The string "acpi genuineintel---intel64-family-6-model-58" is a specific Hardware ID acpi genuineintel---intel64-family-6-model-58

used by the Windows operating system to identify processors based on the Intel Ivy Bridge

architecture. It is typically found in the Device Manager or system logs when a driver is missing or being identified. Technical Breakdown

: Advanced Configuration and Power Interface, the standard for hardware discovery and power management. GenuineIntel : Indicates the processor is manufactured by Intel. Family 6, Model 58 : This specific pairing (Model 58 is in hex) identifies 3rd Generation Intel Core (Ivy Bridge) processors. : Confirms the processor supports 64-bit architecture. Common Associated Processors

This ID is shared across several popular Ivy Bridge CPUs released around 2012–2013, including: Intel Core i7-3770K Mobile (Laptops) Intel Pentium 2117U : These CPUs usually feature integrated Intel HD Graphics 4000 HP Support Community How to Fix "Unknown Device" Issues

The text ACPI\GenuineIntel_-_Intel64_Family_6_Model_58 is a hardware ID used by Windows and other operating systems to identify a specific processor for driver management and power configuration. Technical Breakdown Linux kernel has excellent support:

ACPI: Standing for Advanced Configuration and Power Interface, this prefix indicates the operating system is communicating with the processor through the system's BIOS/UEFI ACPI tables for power management (like sleep states and frequency scaling). GenuineIntel: Confirms the manufacturer is Intel.

Intel64 Family 6: Refers to the microarchitecture family. Nearly all modern Intel processors since the Pentium Pro fall under "Family 6".

Model 58: This specific code identifies the processor generation. Model 58 (3Ah) corresponds to the Ivy Bridge architecture, typically found in 3rd Generation Intel Core processors (e.g., Core i5-3470 or i7-3770). Common Occurrences

You likely encountered this text in one of the following places:

Device Manager: Under the "Processors" section, looking at the "Hardware IDs" in the Details tab.

Event Viewer: In error logs or informational messages related to system boot or power transitions.

Linux Boot Logs: Often seen in dmesg or /proc/cpuinfo when the kernel initializes CPU cores. Troubleshooting However, Ivy Bridge lacks some newer power features

If you are seeing this in a "driver error" or "system hang" context:

Slow Boot/ACPI Errors: This can happen if the OS (especially Linux) has trouble parsing the motherboard's ACPI tables. Updating your BIOS/UEFI from the motherboard manufacturer's website is the primary fix.

Missing Drivers: Windows usually handles this automatically. If you see a yellow exclamation mark in Device Manager, install the Intel Chipset Device Software from the Intel Support site.

This is a detailed technical deep dive into the ACPI identifiers GenuineIntel, intel64, family 6, and model 58 (0x3A). This combination points to a specific, well-known Intel CPU microarchitecture.

ACPI needs to know the precise CPU model for several reasons:

If the ACPI reported model (via _MAT or _PDC) does not match the actual CPUID, the kernel may fall back to generic drivers, losing performance or power savings.

This is the CPU vendor ID returned by the CPUID instruction (EAX=0). For Intel processors, EBX=0x756e6547 ("Genu"), EDX=0x49656e69 ("ineI"), ECX=0x6c65746e ("ntel"). Concatenated, they spell "GenuineIntel".

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.
