Discussed with Hui Wang, for n2d-standard-4.sev_snp with j/gcp-6.8, this issue was found in s2025.02.10 with j/gcp-6.8.0-1027.29~22.04.1 and 2025.03.17 with j/gcp-6.8.0-1028.30~22.04.1. Before that it's OK.
However a manual test shows this can be reproduced with j/gcp-6.8.0-1026.28~22.04.1 on n2d-standard-4.sev_snp. So I think it's safe to call this flaky on it as well. -- You received this bug notification because you are a member of Canonical Platform QA Team, which is subscribed to ubuntu-kernel-tests. https://bugs.launchpad.net/bugs/2089721 Title: mem-on-off-test from memory-hotplug in ubuntu_kernel_selftests fails with timeout while offlining (Flaky) Status in ubuntu-kernel-tests: New Bug description: Flaky timeout failure was observed on builder-cpu2-ram4-disk20. mem-on-off-test from memory-hotplug fails with timeout (without blocked task (ref.
