[Ilya Murav'jov <muravjov.il@xxxxxxxxx>]

Have this bug with my Bluetooth mouse, aftere resume-wake and mouse
activity. Workaround: before mouse activity turn off bluetooth
connection via GUI, so bluetooth status icon does not have small padlock
in it.

I tested issue with trusty and vivid kernels.
