I'm marking this high severity because we get ABRT notifications on both KDE and GNOME for each of these warnings, which is pretty spammy and violates a Final criterion - https://fedoraproject.org/wiki/Fedora_33_Final_Release_Criteria#SELinux_and_crash_notifications: "There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop."

so I'm also proposing this as an F34 Final blocker.

Also MATE and Xfce.

Should this be closed?  I'm not seeing this with 5.11.0-0.rc4.129.fc34.x86_64.
Comment 4 Adam Williamson 2021-02-05 00:14:46 UTC 
Well, it may only happen on debug kernels. But I'm not seeing it logged in today's openQA results either, so let's say it's gone; if anyone sees it again, re-open the bug. Thanks!
