Public bug reported:

The following spam litters dmesg:

[36294.989706] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it known.
[36294.995650] atkbd serio0: Unknown key released (translated set 2, code 0xbe 
on isa0060/serio0).
[36294.995661] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it known.
[36296.016998] atkbd serio0: Unknown key pressed (translated set 2, code 0xbe 
on isa0060/serio0).
[36296.017002] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it known.
[36296.021894] atkbd serio0: Unknown key released (translated set 2, code 0xbe 
on isa0060/serio0).
[36296.021907] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it known.

As can be seen, this occurs frequently. It might be related, but at
times, the keyboard freezes for a few seconds and then starts sending a
repeating character while no keys are pressed. This behavior is not
stopped unless a key (any key) is pressed.

The character that is output is a special character, but I don't know
what combination it is specifically.

This might be related to the fact that this is a lenovo yoga 13 ideapad.
