Comment 1 Chuck Ebbert 2015-09-03 18:47:28 UTC

Did the keyboard work on earlier 4.1.x kernels (4.1.0 - 4.1.5)?

That message was added in 4.1.6 via:

Comment 2 Elias Probst 2015-09-06 08:48:13 UTC

I assumed this was fixed in your referenced commit, but I can still see it on:
- bluez-5.34.0
- Kernel 4.2-rc6

After connecting my "Microsoft Designer Mouse", it is instantly disconnected again and "journalctl -n10 -f -k" shows:
Sep 06 10:44:50 moria kernel: Bluetooth: SMP security requested but not available
Sep 06 10:44:53 moria kernel: Bluetooth: HCI request failed to create LE connection: status 0x0c
Sep 06 10:44:53 moria kernel: Bluetooth: SMP security requested but not available
Sep 06 10:44:53 moria kernel: Bluetooth: SMP security requested but not available
Sep 06 10:44:57 moria kernel: Bluetooth: SMP security requested but not available

… each time a new line like this is is logged, another connect/disconnect cycle happens (according to "bluetoothtl"'s output).

*********** 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.

This bug is being closed with INSUFFICIENT_DATA as there has not been a response in over 4 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
