Comment 9 for bug 1627474

I hope this is helpful additional data. I run Ubuntu 16.04 on a Dell XPS 15 9560. I've been using a bluetooth mouse almost daily for over a month with no problems. I left the computer on, but didn't use it for several days. I then closed the lid (causing a suspend state), later opened the lid to a frozen OS (the clock in the system tray was frozen to about the time I closed the lid). I had to hard-power-off, and have since rebooted, installed updates, rebooted again, and the network seems to work fine, but the bluetooth is no longer recognized at all. I got the same errors reported above after powering up post-freeze.

The syslog with the errors is attached. It is possible that my problem my have arisen from corruption to something when the machine froze, and is not the same consistent kernel bug described above. In either case, I'm hopeful the information posted here and attached provides value.
