Created attachment 807962 [details] ACPI dump from affected machine
Base on dsdt, firmware generated invalid Processor ID after 8 threads. All of them are 0xFF: Device (SCK0) { Name (_HID, "ACPI0004" /* Module Device */) // _HID: Hardware ID Name (_UID, "CPUSCK0") // _UID: Unique ID Processor (CP00, 0x00, 0x00000410, 0x06){} Processor (CP01, 0x02, 0x00000410, 0x06){} Processor (CP02, 0x04, 0x00000410, 0x06){} Processor (CP03, 0x06, 0x00000410, 0x06){} Processor (CP04, 0x01, 0x00000410, 0x06){} Processor (CP05, 0x03, 0x00000410, 0x06){} Processor (CP06, 0x05, 0x00000410, 0x06){} Processor (CP07, 0x07, 0x00000410, 0x06){} Processor (CP08, 0xFF, 0x00000410, 0x06){} // the 9 CPU ... It violates ACPI space. Base on ACPI spec, the ProcessorID must be a unique value: Declares a named processor object named ProcessorName . Processor opens a name scope. Each processor is required to have a unique ProcessorID value that is unique from any other ProcessorID value. -- You are receiving this mail because: You are on the CC list for the bug.
