I am using a bluetooth mouse. After some time (more or less 30 minutes) bluetooth turns off and I should turn on and pair the mouse again.
Sometimes even the wing panel icon disappear and I have to go to settings, where it looks like in the attachement. and turn on off and on combination to get it work again.
It's started like one month ago more or less. (elementaryOS loki 0.4)
dmesg log after the turning off:
