fedora4 에서 yum 으로 커널 패치 후 이상..

최초 fedora 설치시 정상적으로 보이던 CPU 가

#]yum update kernel

이후 top 에서 1개로 보입니다.

해서 커널을 삭제하고

#]yum install kernel-smp 해서 재설치를 했는데도 top에서 여전히 1개로 보이네요.

원래는 DUAL CORE , DUAL CPU 로 알고 있습니다.

어디서 해결을 해야할지 잘 모르겠습니다.

아래는 차례대로  top 의 결과  /etc/grub.conf 의 내용과 dmesg 의 내용, 그리고 /proc/interrupts 의 내용입니다.
