Hi,
When my keyboard enters stand-by and disconnects from the computer I see
high cpu usage by bluetoothd. Sometimes, not always, if I don't wake up
the keyboard, bluetoothd will crash leaving this in /var/log/messages:
Oct 28 18:04:49 localhost kernel: [27658.431018] hid-generic

There are no such problems with the mouse, which, as well as the keyboard,
enters stand-by if not used. I have bluez 4.101 provided by Sabayon Linux.
I don't know if it is related, but there is also a problem with the
keyboard state after starting bluetoothd. The initial state of the
keyboard is "disconnected" which is correct. After hitting a key the
keyboard tries to connect, state changes to "connected" but keyboard
doesn't work and nothing is printed in the logs. If I do a disconnect from
the KDE's bluedevil interface, or from the console by running "hcitool dc
7C:1E:52:A8:47:74" and than hit a key again, the keyboard is correctly
detected and working.
I have this bluetooth keyboard:
