Description Bojan Smojver 2016-05-19 05:56:18 UTC 
Description of problem:
Upon resume, bluetooth mouse (in this case Logitech M337) does not connect any more. Only trackpad available on this ThinkPad T450s.

Version-Release number of selected component (if applicable):
kernel-4.5.4-200.fc23

How reproducible:
Always.

Steps to Reproduce:
1. Boot, use mouse.
2. Suspend/resume.
3. No mouse (bluetooth connection does not appear).

Actual results:
Mouse unavailable.

Expected results:
Works with 4.4.9-300.fc23.

Additional info:
Quick search suggests 2ff13894cfb877cb3d02d96a8402202f0a6f3efd as the start of "bad" commits related to Bluetooth problems. See: http://lkml.iu.edu/hypermail/linux/kernel/1602.2/02725.html. Not Fedora specific, so I'm guessing this would be affecting F-24 and rawhide too.

See Fedora bug: https://bugzilla.redhat.com/show_bug.cgi?id=1336297

Note that restarting bluetooth.service after resume bring everything back to normal.
