I reported this in Fedora 23 as well (https://bugzilla.redhat.com/show_bug.cgi?id=1360705). But reposting here: 1. I think it's a regression in kernel version 4.6, caused by the cpufreq changes. Article on cpufreq changes: https://lwn.net/Articles/682391/ First kernel version reporting this in ABRT: 4.6.0-0.rc6.git0.1.fc25 2. This happens on resume from suspend. On my Thinkpad X201, I can reproduce it reliably if I plug in to mains power, close the lid to trigger suspend, unplug from mains power, and then wake the system up again.
Looks like upstream are aware, with some progress for a fix to be submitted to upstream stable trees. https://lkml.org/lkml/2016/6/27/704

Hello, Following the tip, I found https://patchwork.kernel.org/patch/9199789/ shows State Accepted, archived and looks like that is in kernel-4.7.0 : https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/diff/drivers/cpufreq/cpufreq.c?id=v4.7&id2=v4.6 So I built kernel-4.7.0-2 on copr https://copr.fedorainfracloud.org/coprs/sergiomb/builds_for_Stable_Releases/ copied src.rpm for koji [1] I testing ATM , after after 2 or 3 resumes , seems that is no more ooops.

You can install 4.7.0-2 that is already built in koji. Also, while it is great that you took the initiative and we appreciate the testing, the more people do these micro-fork kernel builds in COPR, the more we have a proliferation of kernels from random places. That isn't sustainable in the long run.

It doesn't need to be built for f23 or f24. The f25 version built in koji will work just fine on either release.
From devel Mailing list you also got that builds in https://copr.fedorainfracloud.org/coprs/jforbes/kernel-stabilization/builds/ OK, I will remove my build from copr. Thanks ,
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 24 kernel bugs. Fedora 24 has now been rebased to 4.7.4-200.fc24. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 25, and are still experiencing this issue, please change the version to Fedora 25. If you experience different issues, please open a new bug report for those.
Summary: the WARNING has gone away now. Ervin hasn't commented recently. It'd be nice if someone with access could close the bug, thanks :).
This specific warning is fixed
