Bug Description
Bluetooth receiver doesn't connect with kernel after sleep/boot-up. The receiver is awake because "kernel: [339132.269449] Bluetooth: hci0 ACL packet for unknown connection handle ##" appears in the system log because I'm shaking the mouse.
Sometimes it takes over 4 minutes of shaking to reconnect the mouse.
I do not know where to report this bug.
Is it the kernel? Because it's the kernel that report that something is happening on the bluetooth receiver.
Is it HCI? Because if I reset hci0, I have to shake the mouse again.
Is it the hardware driver that enter sleep mode incorrectly?
And finally, is it the bluetooth stack?
This machine runs Ubuntu 16.04 but I've had this problem as long as I've had this computer. It's a Lenovo G50-45 with a Realtek 8723BE Wifi/Bluetooth combo HARDCODED into the BIOS (It will not boot if you change the network card to something else, like Intel 7260).
