Bluetooth keyboard disconnects, bluetoothd seems to crash, etc. Do you need any further information to help debug this? This bug makes the bluetooth keyboard unusable.

I use a bt mouse and OEM bt keydock (Asus T100-CHI) Starting with 4.4 thru 4.6-rc1-next*, I have to open blueman's device manager to search for devices after idle timeouts. I also need to leave the device manager dialogue open/minimized to prevent rapid loss of connection. Device pairing is remembered, but manually searching is difficult when the pointing devices stop working. My test setup has a usb mouse as a workaround. dmesg has "unknown main item tag 0x0" after each idle timeout". If I move mouse during boot, it will auto-connect, but it then suffers a rapid timeout soon after booting. See dmesg posted at #114561. It looks like something is incrementing the bluetooth input assignment # when anything times out.

See this commit. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?id=c4c285da1ee18582ace366f07e56e355c20ebc49 which is in kernel 4.15. You could try adding the quirk for your device. (No kernel maintainer has acknowledged this bug report.)

I have similar symptoms with "unknown main item tag 0x0" message after timeout. But my problem is that bluetooth keyboard disconnects on timeout (which is normal), but then, on the first key press it's just loss, while the keyboard reconnects successfully. It doesn't occurs on the same system with Windows 10 - the key doesn't lost on reconnect. I wonder if it can be the same problem.
