Acpi Genuineintel---intel64-family-6-model-58 Patched Jun 2026
: Model 58 introduced RdRand , a dedicated digital random number generator implemented directly on the silicon die for cryptographically secure encryption keys.
The specific "stepping" or design revision for Ivy Bridge chips. 🛠 Why You Are Seeing This Identifier
Follow these sequential steps to resolve stability issues tied to this hardware ID. Step 1: Update the Motherboard BIOS acpi genuineintel---intel64-family-6-model-58
: This is the most specific part of the identifier. The "Model" number, also from the CPUID instruction, differentiates between different microarchitectures and processor families within the broader Family 6. Model 58 (which is 0x3A in hexadecimal) is the code that positively identifies a processor as belonging to the "Ivy Bridge" microarchitecture.
In Intel's official documentation, denotes the Ivy Bridge microarchitecture. Launched as a "Tick" in Intel's classic "Tick-Tock" development cycle, Ivy Bridge represented a die shrink of the 32nm Sandy Bridge architecture down to 22nm process technology . It also famously introduced the industry's first commercial 3D "Tri-Gate" (FinFET) transistors. : Model 58 introduced RdRand , a dedicated
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.
The string acpi genuineintel---intel64-family-6-model-58 is an unusual but decipherable artifact that points to an being handled by the ACPI subsystem in a Linux environment, possibly with a formatting quirk. It reminds us of the deep integration between CPU microarchitecture, ACPI firmware tables, and the OS kernel. Step 1: Update the Motherboard BIOS : This
It may result from:
In simpler terms: . You are most likely to see this on older workstations running CentOS 7, RHEL 6/7, Debian 8/9, or Proxmox on a Supermicro X9-series motherboard.
