Ubuntu 12.04를 실행하는 Intel Core 2 Q8200 (쿼드 코어) 프로세서가 장착 된 Acer Aspire M5640 / M3640 PC가 있습니다.
이제는 하나의 CPU 코어 만 인식하는 것 같습니다. lscpu
출력 :
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 1
On-line CPU(s) list: 0

L2 cache: 2048K
NUMA node0 CPU(s): 0
나는이 예상 한 것 Core(s) per socket
및 CPU(s)
한 것으로 4
여기에 값으로 표시.
중요한 점은 정기적으로 부팅 할 수 없지만 부팅하는 nolapic
동안 하드 동결을 피 하려면 커널 부팅 매개 변수가 필요하다는 것 입니다.
부팅하면 펌웨어 버전은 Version: R01-C2
네 가지 코어를 모두 사용할 수있는 능력에 대한 모든 의견은 높이 평가 될 것입니다.

lshw -class cpu
커맨드 출력을 추가 했는데 CPU가`Intel (R) 2 Quad CPU Q8200 @ 2.33GHz '인 것 같습니다. 이것이 도움이되는지 모르겠습니다. 12.10 라이브 CD를 사용 해보고 계속 게시하겠습니다.
