Different CPU models have different package C-state limits. Family 6 model 58 needs coordination across cores for package C6/C7.
Introduced as the "Tick" phase in Intel's classic "Tick-Tock" manufacturing paradigm, Model 58 miniaturized the prior 32nm Sandy Bridge architecture to a 22nm die size. This specific family introduced several technical breakthroughs.
The component targets the specific silicon design. Within Family 6, Model 58 specifies mainstream desktop and mobile processors constructed on Intel’s 22-nanometer (nm) Ivy Bridge manufacturing process. Deep Dive into Ivy Bridge (Family 6 Model 58) acpi genuineintel---intel64-family-6-model-58
Decoding Your PC: What is "ACPI GenuineIntel-Intel64 Family 6 Model 58"?
The string "acpi genuineintel---intel64-family-6-model-58" is a specific Hardware ID Different CPU models have different package C-state limits
Is the system having trouble or managing power?
If you have ever dug deep into your Windows Device Manager or system logs and found the string ACPI\GenuineIntel_-_Intel64_Family_6_Model_58 Deep Dive into Ivy Bridge (Family 6 Model
However, if this identifier appears prominently in Windows Event Viewer or on a Blue Screen of Death (BSOD), it usually highlights a breakdown in communication between the operating system, the ACPI subsystem, and the processor.
: Refers to the microarchitecture family. Nearly all modern Intel processors since the Pentium Pro fall under "Family 6".
If you are currently troubleshooting a specific crash, let me know:
The problem is that Intel CPUs evolve rapidly, and each microarchitecture handles power transitions slightly differently. ACPI tables (the DSDT/SSDT) are written by the motherboard vendor (BIOS/UEFI) and are often generic. The Linux kernel, upon boot, reads the ACPI tables, then checks the actual CPUID. When it sees family=6, model=58 , it knows:
