Testing kernels with sporadic issues until heisenbug shows in openQA
This is a follow up to my previous post about How to test things with openQA without running your own instance, so you might want to read that first.

Dimitri John Ledkov: Ubuntu Livepatch service now supports over 60 different kernels
Livepatch service eliminates the need for unplanned maintenance windows for high and critical severity kernel vulnerabilities by patching the GNU/Linux kernel while the system runs. Originally the service launched in 2016 with just a single kernel flavour supported.
Over the years, additional kernels were added: new LTS releases, ESM kernels, Public Cloud kernels, and most recently HWE kernels too.
Recently livepatch support was expanded for FIPS compliant kernels, Public cloud FIPS compliant kernels, and as well I.C.B.M. Z (mainframe) kernels.
