Comment 43 for bug 1413440

My HP Intel laptop drops all USB ports when I use the Bluetooth Internet connection for 30 minutes or so after a wake. I notice that the laptop also seems to be using power whilst suspended sometimes and Hibernate doesn't work. I'm running 18.04 Ubuntu Mate. rmmod and modprobe didn't revive anything on the usual modules but some self reference so cannot easily be removed.

Here is dmesg immediately after the bluetooth connection is lost:
