Would you be able to confirm that the patch provided by Oleg,
referenced solves the issue for you?

https://bugzilla.redhat.com/show_bug.cgi?id=1964036#c1

https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s4.2.2

I guess so, and see you in the conversation, but asking explicitly
anyway.
