Flaky tests, non-linear history, and the sheer scale of the test space require significant human intervention for triaging, filtering, and reporting. The post outlines several improvements: richer contextual data from CI systems (historical trends, flakiness signals), lifecycle tracking of regressions from detection through fix verification (referencing regzbot), and tighter integration of bisection workflows into the reporting pipeline so developers can immediately see whether a regression has been bisected and who is responsible. The ultimate goal is to make regression checking a seamless, scalable part of every kernel developer's workflow. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is regzbot and how does it help track Linux kernel regressions? Regzbot is a tool created by Thorsten Leemhuis that tracks the status of reported Linux kernel regressions by automatically monitoring mailing lists and repositories. It gives visibility into where a regression stands in its lifecycle — from detection and investigation through patching, review, and merge — answering questions like whether a fix has been submitted or merged and whether the regression has cleared after the patch landed. _Kernel developers following regression fixes across mailing lists and repos find the latest regzbot discussions on daily.dev._ ### Why is bisection not always reliable for pinpointing the Linux kernel commit that caused a regression? Bisection assumes a linear repository history and a stable test. When either condition breaks down — non-linear history from merge commits or a flaky test that passes and fails intermittently — bisection results become unreliable or impossible to trust. Many CI systems also run bisection as a separate process, making it hard to correlate a regression report with its bisection outcome without manual cross-referencing. _Engineers debugging kernel regressions track bisection tooling developments and CI integration patterns on daily.dev._ ## Similar posts on daily.dev - [Automate the process to find a regression commit](https://daily.dev/posts/automate-the-process-to-find-a-regression-commit-e67ry9pa3) · Markus Staab · 13 upvotes · 1 comments - [Automated regression testing: A complete introduction](https://daily.dev/posts/automated-regression-testing-a-complete-introduction-ylcecni2u) · Testim.io · 0 upvotes · 0 comments - [A Better Alternative to Reducing CI Regression Test Suite Sizes](https://daily.dev/posts/a-better-alternative-to-reducing-ci-regression-test-suite-sizes-ulzdrg7zc) · InfoQ · 0 upvotes · 0 comments - [Regression Testing: What it is, why it matters, and how to automate it with CI/CD](https://daily.dev/posts/regression-testing-what-it-is-why-it-matters-and-how-to-automate-it-with-ci-cd-jxfcmsnpm) · CircleCI · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#testing](https://daily.dev/tags/testing), [#cicd](https://daily.dev/tags/cicd) [View this post on daily.dev](https://daily.dev/posts/automatic-regression-handling-and-reporting-for-the-linux-kernel-syoeapho2) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Automatic regression handling and reporting for the Linux Kernel","url":"https://daily.dev/posts/automatic-regression-handling-and-reporting-for-the-linux-kernel-syoeapho2","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/automatic-regression-handling-and-reporting-for-the-linux-kernel-syoeapho2"},"datePublished":"2026-08-11T08:54:47.134Z","dateModified":"2026-08-11T09:23:25.912Z","description":"Regression detection in the Linux kernel CI ecosystem rarely matches the ideal scenario where a failing test cleanly points to a single offending commit.
