|Kernel 5.16 Test Week|
|Date||2022-01-23 to 2022-01-30|
What to test?
This Test Day will focus on the 5.16 Linux kernel. The primary aim is to test on Fedora 35 and 34.
The following cast of characters will be available testing, workarounds, bug fixes, and general discussion:
- Development - Justin Forbes (jforbes)
- Quality Assurance - Sumantro Mukherjee (sumantrom), Geoffrey Marr (coremodule), Kamil Paral (kparal), Adam Williamson (adamw)
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 F35 test day image or Fedora 34 or 35 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 5.16 kernel for an existing installation from F35 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
Kernel builds can be downloaded from Koji using a command-line tool.
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
List available kernel builds
You can list available kernel builds with:
koji list-builds --package=kernel --after="2022-01-20" | grep "5.16"
Download the 5.16 kernel build you wish, for example kernel-5.16.2-300.fc35:
koji download-build --arch=x86_64 kernel-5.16.2-200.fc35
Update your kernel:
sudo dnf update kernel-*.rpm
Fedora Silverblue or Kinoite
Override the kernel:
rpm-ostree override replace kernel-*.rpm
How to test?
Run the tests
- Follow the instructions in this test case. For users running the test day image, the tests are pre-installed in
- Visit the result page and enter your result in the 'Regression' column by clicking Enter result.
- 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.
- While the results from the regression tests are interesting, we are also interested in your overall experience with the new kernels.
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
