이상합니다.
무선랜 설치한 거 말고는 한 게 없는데..
갑자기 다음과 같은 상황이 나타나고 있습니다.
top 결과입니다.

도대체 왜 그런건지 알 수가 없습니다
events/1 이라는 프로세스가 한쪽 cpu를 계속 점유하네요ㅠ.ㅠ
다른 결과들도 올려드려야 하는데 무엇을 올려야 하는지 알수가 없군요.
우선 ps aux 결과입니다.

한시간 전만 해도 안그랬는데,
갑자기 왜 그런걸까요.. 무선랜 설치한게 문제가 있는 건지..
지금 사용하고 있지 않은데도 그렇군요.
리부팅을 해도 처음엔 안그러다가
몇 분후 똑같은 증상이 나타나는군요...
잘 아시는 분 꼭 부탁드립니다..
레댓9 커널2.6.11.5 사용중입니다.
