Description of problem:
since upgrading to fedora 22, these scary message appears in dmesg/syslog:

Version-Release number of selected component (if applicable):
systemd-219-19.fc22.x86_64

How reproducible:
always 

Steps to Reproduce:
1. just look at dmesg
2.
3.

Actual results:
as above.

Expected results:
no such scary messages.

Additional info:
apparently they are harmless and the "fix" in the upstream repport is simply
downgrading the message level from warning to debug. Please backport, etc.
These scary messages aren't really useful when looking at other issues.

Me too. Running 4.0.8-300.fc22.x86_64

I agree -- and I was very pleased to find this report confirming that this is harmless -- after trying to find out what I could have broken.

Thanks!

Comment 2 Fedora End Of Life 2016-07-19 17:08:15 UTC

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
