C1+ kernel panic 증상 문의

Unread post by heavyman » Thu Aug 29, 2019 1:25 pm

안녕하세요.
ODROID C1+ 사용중에 application 실행 중 kernel panic 현상이 발생해서 문의드립니다.
application의 memory 접근 오류에 의해서도 kernel panic이 발생할 수 있는 것인지, 아니면 device driver나 kernel 단에서 발생하는 것인지 분간이 안되어서 문의드립니다.
ODROID에 붙어있는 장치는 USB2Serial 장치, i2c 장치가 연결되어있습니다.

커널 정보는 아래와 같습니다.

Linux odroid 3.10.107-190 #1 SMP PREEMPT Mon Sep 4 20:41:37 UTC 2017 armv7l armv7l armv7l GNU/Linux
kernel panic 발생시에 콘솔창에 뜬 메시지는 아래와 같습니다.

Re: C1+ kernel panic 증상 문의

Unread post by odroid » Thu Aug 29, 2019 2:34 pm

올려주신 내용만으로는 어떤 원인으로 커널 패닉이 발생하는지 알기 어렵네요.
CPU나 RAM 점유율이 높은것으로 보이지는 않습니다.

혹시 Ubuntu 18.04가 아닌 16.04를 사용하시는 특별한 이유가 있는지요?

그리고 CPU governor를 performance mode로 변경해서 테스트 해보시길 바랍니다.

2017년에 출하된 장비에 탑재된 ODROID C1+입니다.
필드에서 사용중에 문제가 보고되어 회수해서 테스트한 결과 올린것과 같은 문제가 확인되었습니다.

올려주신 링크에서 보고 CPU governor를 performance mode로 변경해서 테스트한 결과 동일하게 kernel panic이 발생했습니다.
이건 어떤 효과를 기대하고 권해주신건가요?

일부 USB 장치들의 IRQ handler 응답이 느린경우 커널 패닉이 발생한다는 사용자들이 performance governor로 변경해서 문제를 해결했다는 리포트가 많아서 말씀드렸습니다.

여러대의 C1+중에 특정 보드만 문제가 있다면 CPU나 RAM의 일부가 손상되었을 가능성도 있겠네요.
"stress-ng" 패키지를 설치하시고, 아래 명령어로 안정성 테스트를 해보시길 바랍니다. 4분 정도 소요되는 테스트 입니다.
stress-ng --cpu 4 --io 2 --vm 1 --vm-bytes 512M --timeout 60s --metrics-brief

stress-ng 테스트 결과입니다.

1. application이 실행 중인 상태에서 application의 동작을 중단하고 stress-ng 테스트를 실행하니 아래와 같은 kernel panic 메시지가 나왔습니다.

Code: Select all

Re: C1+ kernel panic 증상 문의

Unread post by odroid » Fri Aug 30, 2019 3:27 pm

application의 memory leak이나 allocation에 의한 문제이거나 보드의 RAM에 HW 문제가 있을수도 있겠습니다.
모든 보드의 증상이 동일한가요? 아니면 특정 보드에서 나타나는 현상인가요?

보드1 : 문제 발생 보드
보드2 : 개발 보드
eMMC1 : 문제 발생 보드의 eMMC
eMMC2 : 개발 보드의 eMMC
eMMC1과 2의 커널 버전은 같습니다.

위 보드와 eMMC로 4가지 조합으로 아래 명령으로 부하 테스트의 제한 시간 없이 테스트했습니다.
모두 application은 실행하지 않은 상태입니다.

Re: C1+ kernel panic 증상 문의

Unread post by odroid » Fri Aug 30, 2019 6:03 pm

18.04 minimal image를 micro-SD에 새로 설치후 전체 시스템 업데이트를 하였습니다.
커널 버전은 3.10.107-13이고 우분투 버전은 18.04.3이 되었습니다.

동일한 명령어를 실행하고 htop으로 상태를 보니 CPU 4개에 로드가 꽉 차고 메모리 사용량은 646MB 정도까지 올라갔습니다.
시작한지 20분 정도 되었으며 화요일까지 테스트를 걸어 놓고 결과 공유하겠습니다. 제가 월요일은 외근이라서...

40pin header의 5Volt 레일을 DMM으로 찍어보니 4.98V 나오네요.
전원쪽 안정성도 한번 확인해 보시길 바랍니다.

Re: C1+ kernel panic 증상 문의

Unread post by heavyman » Mon Sep 02, 2019 7:21 pm

stress-ng 추가테스트를 진행했습니다.
1. 40pin header에서 측정한 전압은 4.85V 나옵니다.

2. Ubuntu 16.04.3(v2.2)을 설치하고, stress-ng 만 설치해서 테스트했을 때 문제가 계속 발생했습니다.

3. Ubuntu 18.04.1(v3.0)을 설치하고, stress-ng 만 설치해서 테스트했을 때 문제가 발생할 때도 발생하지 않을 때도 있습니다.
중간에 kernel panic이 발생할 때도 있고 발생하지 않을 때도 있는데, kernel panic이 발생하지 않을 때도 stress-ng-vm에서 에러는 발생합니다.

Re: C1+ kernel panic 증상 문의

Unread post by odroid » Tue Sep 03, 2019 11:20 am

전원 전압이 좀 낮은것 같습니다만, 일정하게 유지만 된다면 큰 문제는 아닐것 같습니다.
4.85V 아래로 떨어지는 경우는 없었나요?

그리고 전원은 DC Jack에 연결하시고 J8 점퍼는 제거한 상태인가요?
https://wiki.odroid.com/odroid-c1/hardw ... wer_enable

저는 4일 가까이 테스트를 돌렸는데 아직까지 별다른 에러는 없습니다.
참, zram-config를 이용해서 ZRAM을 활성화 시키셨나요?

stress-ng 테스트 동작하지 않을 때는 4.92V 측정되고, stress-ng 테스트 중에도 4.85V 아래로 떨어지지는 않습니다.
전원은 DC Jack에 연결되어있고, J8 점퍼는 제거한 상태입니다.

Ubuntu 18.04.1을 설치한 이미지에서는 zram이 기본으로 설정되어 있네요.

Ubuntu 18.04.1에서 stress-ng 테스트를 계속 진행했더니 콘솔창에 에러없이 보드 동작이 중단(파란색 alive led 깜빡이지 않음)되는 증상도 있네요.

그정도 전압 강하라면 전원에 문제가 있을것 같지는 않습니다.
그리고 Blue LED까지 깜빡이지 않는다면 Kernel scheduler까지 죽은것으로 생각됩니다.

올려주신 커널 메시지 중에 ZRAM-SWAP 관련된 내용이 있어 문의 드렸습니다.

번거로우시겠지만, 어제 릴리즈된 Ubuntu 18.04.3 이미지로 테스트 부탁드립니다.
ubuntu-18.04.3-3.10-minimal-odroid-c1-20190828.img.xz
https://dn.odroid.com/S805/Ubuntu/

저희도 시료수를 늘려서 테스트 해보도록 하겠습니다.

Ubuntu 16.04.3에서는 활성화되어 있지 않습니다.
활성화해서 테스트해볼까요?

Ubuntu 18.04.1을 설치해서도 stress-ng 테스트에서 kernel panic 증상이 발생하는데, CPU나 RAM의 단품 결함으로 봐야할까요?
단품 결함이라고 한다면, 진행성으로 발생할 수 있는 것인지 아니면 초기에 결함이 있던 걸로 봐야 하는건지,
초기 결함이라고 한다면, 보드 구매 후에 stress 테스트를 거쳐서 걸러낼 수 있는것인지 궁금합니다.

어제 새로 올린 18.04.3 이미지는 ZRAM이 활성화되어 있지 않습니다.
활성화 시키지 마시고 테스트해보시길 바랍니다.

C1+는 지난 3년간 20만대 정도가 출하되었는데, 이런 현상에 관한 직접적인 레포트를 받은적이 없어 분석에 좀 더 시간이 필요합니다.
최근에 생산한 보드를 Random으로 5개를 골라 최신 Ubuntu 18.04.3이미지로 Stress-ng 테스트를 내일 오전부터 시작해 보겠습니다.

저희는 18.04.3 Minimal을 설치한 5대의 C1+ 에서 아래와 같은 Python 스크립트를 70시간 이상 돌렸습니다만 별 문제는 없었습니다. stress-ng를 반복해서 돌리며 시스템 로그를 기록하는 스크립트입니다.

그러나 18.04.3 Mate에서는 메모리관련 커널 패닉이 빠른 시간안에 발생하였습니다.
x11 desktop이 200MB정도 추가로 점유하고 있어, stress-ng의 --vm-bytes 옵션을 512M에서 256M으로 줄이니 20시간째 잘 돌아가고 있으며 좀 더 지켜볼 예정입니다.

가용 메모리 이상을 침범하면 application 프로그램이 죽거나 에러가 발생하고 멈추어야 할것 같은데, 커널이 죽는 현상은 잘 이해가 안되어 Dynamic memory-allocation 테스트 방법을 찾아보려 합니다.
그리고 혹시 가능하시다면 개발하신 어플리케이션이나 서비스 프로그램에 memory leak 현상이 있는지 점검해 보는것도 의미가 있을것 같습니다.

네. application의 메모리 사용 문제가 있으면 application이 죽어야 하는데 kernel panic이 발생해버리니 이상하네요.
그리고 혹시 가능하시다면 개발하신 어플리케이션이나 서비스 프로그램에 memory leak 현상이 있는지 점검해 보는것도 의미가 있을것 같습니다.

최초에 올렸던 application 동작 중에 kernel panic 발생했을 때 top 화면입니다.
메모리에 여유는 있는것 같습니다.
그리고 application의 메모리 사용량이 많아서 그런가 해서 메모리 사용량을 약 60MB 정도 줄여서 테스트했을 때도 kernel panic이 발생했습니다.
application 개발하면서 메모리 사용량은 굉장히 신경써서 관리하고 테스트하면서 top 명령으로 메모리 사용량이 증가하지 않는지 확인합니다.
혹시나 메모리 사용량이 일시적으로 과도하게 증가하는 경우가 있는지 좀 더 점검해보겠습니다.

16.04.3 Mate에서 stress-ng 메모리를 256M로 줄여서 테스트했는데 약 3일 경과후 에러가 발생했고, 오늘 아침에 종료시켰는데 kernel이 죽어있지는 않았습니다.

Re: C1+ kernel panic 증상 문의

Unread post by odroid » Mon Sep 16, 2019 5:32 pm

저희는 memtester라는 프로그램을 Ubuntu 18.04.3위에서 연휴동안 돌려보았는데 별 문제는 없었습니다.
따라서 메모리 인터페이스 드라이버에 의한 문제보다는 메모리 관리자 드라이버에 의한 문제일 가능성이 높아 보입니다.

커널의 메모리 관리자 기능에 언제부터 문제가 발생하였는지 알아보기 위해서 좀 오래된 커널을 사용하는 14.04이미지를 이용해서 테스트를 해보겠습니다.
2주 가까운 시간동안 명확한 해결책을 드리지 못해서 죄송하게 생각합니다.

위는 개발 보드에서 하루동안 저희 application을 돌리면서 top 명령으로 측정한 메모리 사용량입니다.
Application의 메모리 사용량은 더이상 증가하지 않고 일정한데, 시스템 메모리 가용량은 꾸준히 조금씩 줄어들고 있습니다.

stress-ng 테스트는 보드에 따라 결과가 다르지는 않은데, application 테스트 시에는 개발보드에서는 문제가 발생하지 않는데, 필드에서 문제가 발생한 보드에서만 kernel panic이 발생하네요.

필드에서 문제가 발생한 보드를 보내드리면 분석에 도움이 될까요?

Re: C1+ kernel panic 증상 문의

동일한 환경과 어플리케이션이 아니라, 솔직히 말씀드리면 원인 분석이 어려울것 같습니다.
저희가 테스트 완료한 보드를 먼저 보내드릴테니, PM으로 배송 주소와 연락처 부탁드립니다.
오른쪽 아바타 아래에 Contact:말풍선을 누르면 PM이 가능한 것으로 알고 있습니다.

저희는 계속해서 원인을 찾아보도록 하겠습니다.
