Can't make the date?
If you come to this page before or 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 at Bugzilla, 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?

This Test Day will focus on the 5.18 Linux kernel. The primary aim is to test on Fedora 35 and 34.

Who's available

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

You can chat with us on IRC. See the infobox on top of the page to learn the right IRC channel.

Prerequisite for Test Day

  • A fully updated F36 test day image or Fedora 35 or 36 Workstation/Server installation, either on bare metal or VM (please make sure you have no important data on that installation, things might go wrong -- don't do this on your production machine!)
  • The 5.18 kernel for an existing installation from F36 koji (see below) or kernel-stabilization copr if not using the test day image. (koji is recommended for secure boot users).
  • Enough free space on storage.

Koji download instructions

Download Koji

Kernel builds can be downloaded from Koji using a command-line tool.

Fedora Workstation

Install Koji on Fedora Workstation if not installed: 

sudo dnf install koji

Fedora Silverblue or Kinoite

Install Koji on Fedora Silverblue or Kinoite if not installed: 

rpm-ostree install koji

And reboot.

List available kernel builds

You can list available kernel builds with: 

koji list-builds --package=kernel --after="2022-06-07" | grep "5.18"

Download kernel

Download the RPMs for the 5.18 kernel build you want to test to a test directory, for example kernel-5.18.2-201.fc36: 

mkdir -p ~/work/kernel_test
cd ~/work/kernel_test
koji download-build --arch=x86_64 kernel-5.18.2-201.fc36

Install kernel

Fedora Workstation

Update your kernel: 

sudo dnf update kernel-*.rpm

And reboot.

Fedora Silverblue or Kinoite

Override the kernel: 

rpm-ostree override replace kernel-*.rpm

And reboot.

How to test?

Run the tests

  1. Follow the instructions in this test case. 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.

Reporting bugs

Note to Virtualbox users: By default, the insert_leap_second test will fail, this is because Virtualbox syncs the guest time with the host in the middle of the test. This is not a kernel or test suite failure, it is a Virtualbox design issue. It should skip this test if your kernel-tests repo has been updated since 2021-09-12.

If you have problems with any of the tests, have a look in the results page. Please include the vulnerability output at the end of the test suite in the comments.

If you don't see it, please file a new bug to Bugzilla, probably against kernel component. If you are unsure about exactly how to file the report or what other information to include, just ask on IRC #fedora-test-day or #fedora-qa and we will help you.

Revert override on Fedora Silverblue or Kinoite

If you are a Fedora Silverblue or Kinoite user, you can simply revert the override and use the stable kernels again. Run the following command to revert it back: 

rpm-ostree override reset kernel kernel-core kernel-debug kernel-debug-core kernel-debug-devel kernel-debug-modules kernel-debug-modules-extra kernel-debug-modules-internal kernel-devel kernel-modules kernel-modules-extra kernel-modules-internal

And reboot.
