If I disable or uninstall blueman, the mouse doesn't come back to life
after a suspend/resume (or initial bootup) until I manually issue
"hciconfig hci0 up". This is the case for both pre- and post-2ff1389
kernels.

I right-click the blueman systray icon, and it pops up a meny where I
can select either =C2=ABTurn Bluetooth Off=C2=BB or =C2=ABTurn Bluetooth On=
=C2=BB (only one
of the options are shown, depending on blueman's idea of the current
status).

I uploaded debug files to http://filebin.net/pfmb8043cx :

- timestamps.$KVER.txt: my notes of the timestamps of when I did
  specific actions, for easy cross-referencing with the other files.
- blueman-applet.$KVER.txt: output from "blueman-applet |& ts".
- btmon.$KVER.txt: output from "btmon -T".
- kernel-debug-messages.$KVER.txt: kernel output (journalctl -k), after
  having written "module bluetooth +p" to
  the /sys/kernel/debug/dynamic_debug/control file.

Where $KVER is either 4.4.0-rc3-00801-gbf943cb (the last rev where the
bluetooth mouse comes back to life automatically after resume) or
4.4.0-rc3-00802-g2ff1389 (the first rev where it doesn't).

This made no difference. Note that I had to create that file and its
containing directory anew, it didn't already exist on my Fedora 23
system.
