"[ 함수명() ]" 이런식으로 나오는 것은 제가 디버깅 메시지 찍어 준 겁니다.
사실 어느 쪽부터 잡아야 하는지 잘 모르겠습니다. 방향을 집어 주시면 열심히 파보겠습니다. 조언 부탁 드립니다.
커널도 관련이 있을 듯 하고요...커널 버전은요? 2.6인 듯 싶긴 하지만요.
난감한 케이스인데....
제가 회로도랑 여러가지를 파악하기 전에는 애매하네요...
aesop용을 올릴랬더니....분산되어 있어서 여러가지를 올려야 하네요.
난감....
지금상황으로는 schedule쪽에 문제가 있는 것인데, 이런 경우 이유가 굉장히 많습니다.
예를 들어서 timer interrupt service routine안에서 sleep()을
했다던가 하는 경우입니다. 지금 메세지도 그런 경우와 비슷한데...
봐보기전에는 뭐라고 말씀 드리기가 애매하네요.
