Just tested todays git linux-next. Mouse showed same buggy behavior. Lags after 3-5 sec of inactivity. As another possible workaround the following line may be added to /etc/init.d/bluetooth : echo 60 >/sys/class/bluetooth/`readlink /sys/class/bluetooth/hci0`/../../../power/autosuspend for each hci device you have.
