Bluetooth keyboard only works for a few moments

[Andrew Vos]

After a, seemingly random, amount of time my Bluetooth Keyboard stops working. If I look in the Bluetooth tray it seems to be connecting and disconnecting really quickly.

It's an apple magic keyboard. There are absolutely no problem on Ubuntu Gnome 17.04 which is running kernel 4.10.

Please note that in my dmesg log I have plugged the keyboard into USB after trying to get it to work a few times.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Using this kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/

There is a difference when I pair the device it asks me to type in the PIN, where with the previous kernel it just said "is this pin correct".

After a few seconds my keyboard stops working though.

[Andrew Vos (andrewvos)]

I can’t work out how to add the tag kernel-bug-exists-upstream?
