Can't make the date?
If you come to this page after the test day is completed, your testing is still valuable, and you can use the information on this page to test, file any bugs you find, and add your results to the results section. If this page is more than a month old when you arrive here, please check the current schedule and see if a similar but more recent Test Day is planned or has already happened.

What to test?[edit]

This Test Day will focus on the 6.19 Linux kernel. The primary aim is to test it with Fedora 44 and also Fedora 43.

Who's available[edit]

The following cast of characters will be available testing, workarounds, bug fixes, and general discussion:

You can chat with us on Matrix. See the infobox on top of the page to learn where to join.

Prerequisite for Test Day[edit]

  • A virtual machine or a bare metal machine
  • An installation of Fedora 44/43 (any Edition or Spin). Make sure to fully update your system.
    • If installing a fresh system, install using the test day F44 image
    • If using an existing system, the 6.19 kernel from koji 2944717 build (see below, recommended for Secure Boot users) or kernel-stabilization copr
    • Make sure you have no important data on that system. Things might go wrong -- don't do this on your production machine!
  • Enough free space on storage.

Kernel from a Koji build instructions[edit]

Install koji command-line tool[edit]

RPM-based systems (Workstation, Server, etc) 

sudo dnf install koji

Atomic systems (Silverblue, Kinoite, Sericea, Onyx, CoreOS, IoT, etc)

Install Koji in a toolbox: 

toolbox create
toolbox enter
sudo dnf install koji

Or directly on the host: 

rpm-ostree install koji

And reboot.

List available kernel builds[edit]

You can list available kernel builds with: 

koji list-builds --package=kernel --after="2026-02-18" --pattern "kernel-6.19*"

Download kernel[edit]

Download the RPMs for the 6.19 kernel build you want to test to a test directory, for example kernel-6.19.3-300.fc43: 

mkdir -p ~/work/kernel_test
cd ~/work/kernel_test
koji download-build --arch=$(uname -m) kernel-6.19.4-300.fc43

Install kernel[edit]

RPM-based systems (Workstation, Server, etc)

Update your kernel: 

sudo dnf update kernel-*.rpm

And reboot.

Atomic systems (Silverblue, Kinoite, Sericea, Onyx, CoreOS, IoT, etc)

Override the kernel: 

rpm-ostree override replace kernel-modules-core-6*.rpm kernel-core-6*.rpm kernel-modules-6*.rpm kernel-6*.rpm kernel-modules-extra-6*.rpm

And reboot.

How to test?[edit]

  1. Follow the instructions in QA:Testcase kernel regression. For users running the test day image, the tests are pre-installed in /home/liveuser/kernel-tests/.
  2. Visit the result page and enter your result in the 'Regression' column by clicking Enter result.
  3. If there are any other result columns, click on the column title links to see the tests that need to be run: most column titles are links to a specific test case. Follow the instructions there, then enter your results by clicking the Enter result button for the test.
  4. While the results from the regression tests are interesting, we are also interested in your overall experience with the new kernels. You can put those under QA:Testcase Exploratory Testing.

Reporting bugs[edit]

Known bugs[edit]

Please feel free to comment on the existing bugs with your results and hardware specifications. It is currently unclear which specific hardware configuration or settings are required to reproduce the issue.

Or perhaps you've found a different already-reported bug. Please look at:

New bugs[edit]

All new bugs should be reported to Bugzilla, probably against kernel component.

We really need bug reports!
Please note that just mentioning your problem into the comments section on the results page is not very helpful. Very often those problems only happen in specific circumstances, or with specific steps taken. We need the logs and screenshots, and we need to be able to ask you followup questions. Please file bug reports, it's much more useful than a short comment. Thank you!

When filing the bug, it's very helpful to include:

  • exact steps you've performed (and whether you can reproduce it again)
  • screenshots or videos, if applicable
  • system journal (log), which you can retrieve by journalctl -b > journal.txt
  • all output in a terminal, if started from a terminal
  • your system description

If you are unsure about exactly how to file the report or what other information to include, just ask us.

Please make sure to link to the bug when submitting your test result, thanks!

After testing: Revert override on atomic systems[edit]

If you are on an atomic system (Silverblue, Kinoite, Sericea, Onyx, CoreOS, IoT, etc), you should revert the override and use the stable kernels again. Run the following command to revert it back: 

rpm-ostree override reset kernel-modules kernel-modules-extra kernel-core kernel kernel-modules-core

And reboot.
