*********** 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 20 kernel bugs. Fedora 20 has now been rebased to 3.14.4-200.fc20. 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 experience different issues, please open a new bug report for those.
Description of problem: Trying to connect a bluetooth mouse (Logitech MX1000) to the system using the KDE bluetooth configuration dialogs. Steps to reproduce: - Click on bluetooth icon on tray -> "Add device" - Turn mouse power on The error is reproducible every time and has happened before, on a couple of different kernel versions.
