This morning I tried to use my laptop. I think it was suspended, but not deep suspended (screen off, but was attached to AC). When I tried resuming it, the screen went on, but instead of the gnome login, I was greeted by a black screen with some errors.
```
Bluetooth: hci0: Timed out waiting for suspend events
Bluetooth: hci0: Suspend timeout bit: 6
Bluetooth: hci0: Suspend notifier action (3) failed: -110
```
As I could do nothing, I rebooted the laptop (force off with power button and turned on).
As I logged in, the Bluetooth indicator in the top right panel started appearing and disappearing continuously. I normally have a Bluetooth mouse connected, so I thought it was trying to pair with it. So I went into the Bluetooth tab from Settings and I was asked permission to pair the device. After allowing that permission appear / disappear issue went out.
I think something is wrong with this flow. I think the service for the Bluetooth should handle these issues better, not blinking, but asking such permission that it required from the beginning. As it is it looks broken and poorly discoverable.

Three issues here:
1. The log messages you mention are from the kernel, and probably not important.
2. The flickering GUI is definitely a bug, and is perhaps in libgnome-bluetooth (?)
3. The bug is currently assigned to 'bluez' which is probably not to blame.
