일반 파일 wrte 중 발생하는 커널 패닉은 어떻게 디버깅을 해야 하나요?

카메라 모듈을 구동하면서 LCD에 영상을 출력합니다.
동사에 영상 데이터를 압축해서 파일로 저장하는데
카메라 모듈이 구동되는 중에 파일을 write하면 아래와 같은 에러 메세지와 함께 커널이 죽어 버립니다.
이런 경우 디버깅을 어떻게 해야하나요?
커널 버전은  2.6.21입니다.
크로스 컴파일은 4.3.1-eabi-armv6 입니다.
현재 테스트는 NFS 환경 및 램디스크에서 해봤습니다.
저장 매체는 NFS 서버와 SD메모리에 해봤는데
NFS 환경이든 램디스크 환경이든 에러는 동일합니다.
데이터 저장을 NFS 서버에 할 경우에 좀더 빈도수가 적게 나타나더군요.

디버깅을 해봐야하는데 어디에서 부터 어떻게 할지 난감하군요.
