Description of problem: I am not sure what happened yet. I have noticed that since my upgrade to Fedora 22, I frequently experience complete lock-ups. There is not response from mouse or keyboard any more. Music that was playing loops over the last half a second or so. My only option to recover is a hard reboot. In the backtrace I see there is mention of hid_disconnect. Perhaps the issue is triggered by my bluetooth Apple Trackpad. I have had several occasions the lock-up happened while using it (for scrolling, two-finger-clicks,...). It's not always happening though. I haven't found a way to consistently repeat it.
