ACPI is not just about suspending to RAM. It controls:
Sometimes users see this string adjacent to an error like:
| Attribute | Value | |-----------|-------| | Vendor String | GenuineIntel | | Arch | intel64 | | Family | 6 | | Model | 58 (0x3A) | | µarch | Ivy Bridge | | Lithography | 22 nm | | Max cores | 4 (client) / 10 (server) | | HT | Yes | | EIST | Yes | | C-states | C1, C6 | | Package C-state | PC6 | | ACPI P-state method | MSR 0x199 | | MWAIT hint for C6 | 0x20 | acpi genuineintel---intel64-family-6-model-58
Thus, the pattern is permanent. If you are writing scripts or log parsers that match this string, like:
