[Bug 1913188] Re: linux-hwe 4.15.0-133.137~16.04.1 ADT test failure with linux-hwe ubuntu_qrt_kernel_panic
Hello Steve, this timeout I believe is not a strict limitation. I am not sure if I understand your "or is it not seeing forward progress via output to stdout?" correctly, this timeout is implemented in the autotest framework, if the test didn't finish in time, it will be killed and emit this timeout error.

Hi, The particular test that is timing out actually is supposed to emit periodic output to stdout; it basically is running the test program from kernel commit b4a1b4f5047e4f54e194681125c74c0aa64d637d 10 times and attempts to emit a count every 1000 iterations, writing to and flushing stdout. The test itself spins up four threads that do keyctl_read() and keyctl_revoke(), to try to trigger a race condition in the kernel. Is the test timeout a strict timeout, or is it not seeing forward progress via output to stdout? I know in the kernel autotests stdout gets buffered in some way, so I could adjust the script to emit the counter to stderr instead, if that would help indicate that forward progress is being made. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913188 Title: linux-hwe 4.15.0-133.137~16.04.1 ADT test failure with linux-hwe ubuntu_qrt_kernel_panic To manage notifications about this bug go to: https://bugs.launchpad.net/qa-regression-testing/+bug/1913188/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This testcase hasn't been changed in several months, so we can discard any recent testcase change causing the timeout. However, looking at the logs for focal/linux-hwe-5.8 runs on arm64 there are some interesting data. The last time the testcase was successful was with version 5.8.0-36.40~20.04.1: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-focal/focal/arm64/l/linux-hwe-5.8/20210108_133824_09617@/log.gz Looking at the timestamps the test took a little bit over 19 min to finish. Starting from version 5.8.0-37.42~20.04.1 it stated to fail: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-focal/focal/arm64/l/linux-hwe-5.8/20210113_031753_cd06b@/log.gz The timeout reached was 1200 sec, i.e. 20 min. This test has been running for a little under the timeout limit for the slower architectures, and at least for hwe-5.8 the changes introduced after -36 could not explain any change on the execution time of this testcase. Therefore, I believe these failures have been caused by variations on the test systems and the testcase timeout should be adapted for expected longer runs. ** Also affects: ubuntu-kernel-tests Importance: Undecided Status: New ** Also affects: qa-regression-testing Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913188 Title: linux-hwe 4.15.0-133.137~16.04.1 ADT test failure with linux-hwe ubuntu_qrt_kernel_panic To manage notifications about this bug go to: https://bugs.launchpad.net/qa-regression-testing/+bug/1913188/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
