Comment 3 Laura Abbott 2017-01-17 01:21:14 UTC
*********** 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 25 kernel bugs.
 
Fedora 25 has now been rebased to 4.9.3-200.fc25.  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 26, and are still experiencing this issue, please change the version to Fedora 26.
 
If you experience different issues, please open a new bug report for those.

I've updated both my Fedora 25 systems to the current kernel. I haven't seen this issue since the initial finding / report. And I don't know how to trigger it.

I'll try a stress test - a big download or repeated WiFi speed tests - and see if I can trigger it.

Comment 5 M. Edward (Ed) Borasky 2017-04-17 23:51:03 UTC
I can't reproduce this - you can close it as far as I'm concerned.
