Public bug reported:

Binary package hint: bluez

Connection drops after a few minutes. Then after pressing a few keys,
the connection goes up again. Mostly seems to happen when there is a
short few second typing pause. This also drops other bluetooth devices,
such as the Logitech bluetooth mouse, which need to reconnect.

Using 10.04 64bit.

dmesg is filled with these during every drop (here you see two
connection drops):
