Source: stress-ng Version: 0.11.01-1 Severity: serious Tags: sid bullseye X-Debbugs-CC: debian-ci@lists.debian.org User: debian-ci@lists.debian.org Usertags: flaky Dear maintainer(s), The autopkgtest of stress-ng turned up a couple of times on our list of unfinished tests on the ci.debian.net arm64 infrastructure. I looked into the history of your autopkgtest and it fails regularly on arm64 [1][2]. Looking at the purpose of this package, is it possible that it's a bit too aggressive for the workers of ci.debian.net? Especially if you consider that we run several autopkgtest instances in parallel on the same host? Because the unstable-to-testing migration software now blocks on regressions in testing, flaky tests, i.e. tests that flip between passing and failing without changes to the list of installed packages, are causing people unrelated to your package to spend time on these tests. Furthermore, I have the (not further substantiated) impression it's impacting our ci service. I copied the output at the bottom of this report. Not all the failing tests [1][2] that I inspected fail at the same position. Please do get in touch if we need to dive into this together.
