Description of problem:
On rasberrypi2 running F25 beta (installed from Fedora-Workstation-armhfp-25_Beta-1.1-sda.raw.xz) the logs get filled with warnings, about 1000 per hour.

I think it is triggered by network activity.
Version-Release number of selected component (if applicable):
Linux version 4.8.2-300.fc25.armv7hl
Steps to Reproduce:
1. Install F25 beta to a raspberrypi2
2. Check logs
I think the raspbian kernels have this patch to remove the message:
> I think it is triggered by network activity.
No, it's triggered by the vc4 display driver. It's not really a major issue as it's more informational than a bug. I think it might be fixed in 4.9.10 so you might like to retest with that.
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
