Ubuntu 12.04를 실행하는 Intel Core 2 Q8200 (쿼드 코어) 프로세서가 탑재 된 Acer Aspire M5640 / M3640 PC가 있습니다.
이제는 하나의 CPU 코어 만 인식하는 것 같습니다. lscpu

나는이 예상 한 것 Core(s) per socket

한 것으로 4
여기에 값으로 표시.
중요한 점은 정기적으로 부팅 할 수 없지만 부팅 nolapic
중 하드 멈춤을 방지 하려면 커널 부팅 매개 변수가 필요하다는 것 입니다.
부팅과 관련하여 펌웨어 버전은 다음과 같습니다. Version: R01-C2
4 개의 코어를 모두 사용할 수있는 능력에 대한 모든 생각은 높이 평가 될 것입니다.
