Please integrate spec file/patches from:

Includes also b53 switch from OpenWRT so that Banana Pi-R1 works well
Comment 2 Peter Robinson 2015-08-21 09:48:12 EDT
We won't be integrating any patch that's not already headed upstream. Sorry, there's just not enough people to support that.

I will review the hstimer issue once I get time but as it's purely just dmesg spam it's not my current priority

*********** 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 22 kernel bugs.

Fedora 22 has now been rebased to 4.2.3-200.fc22.  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 23, and are still experiencing this issue, please change the version to Fedora 23.

If you experience different issues, please open a new bug report for those.
