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:

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:

Could you please try to get a proper backtrace of what's happening.
I.e. run bluetoothd with valgrind or gdb, e.g.:
sudo killall bluetoothd
sudo valgrind /usr/sbin/bluetoothd -nd
If this doesn't give useful info because of missing debug symbols either
try to install them (no idea how to do that with your distro though) or
compile and run 4.101 from the source tree (no need to install the
custom compilation on your system).
The HCI-level log would also be helpful in addition to the bluetoothd
debug logs, so please run "hcidump -X" in a separate terminal while
reproducing the issue. Thanks.
Johan
