안녕하세요^^

UDP소켓을 통해서 1초마다 데이터를 송수신하고 있습니다. 한 3시간~12시간 사이에 다음과 같은 커널 패닉이 발생합니다.

고수님들의 분석 좀 부탁드리겠습니다.

CPU : intel PXA320

OS : Linux Kernel - Embedded Linux Kernel 2.6.21 version
디바이스 드라이브 insmod 는 부팅시에 호출되는 shell script에 의해
디바이스 드라이브 mknod는 실행프로그램에서 실행

감사합니다.

로그내용을 바서는 파일접근시 에러가 난것 같군요

작성하신 드라이버는 올리지 마시고 테스트하세요

동일한 에러가 발생한다면 드라이버 문제는 아니겠죠.

질문주신 내용만으로 에러는 판단하기 어렵네요

파일시스템을 램디스크로 사용한 상태에서 테스트 해보세요

의심되는 모든 것들을 하나씩 제거하면서 테스트 해야 할것 같습니다.
