After the latest update, bluetooth is working without a problem. No workaround is required. However, bluetooth breaks after suspend resume. Following is a hcidump of a suspend resume action.

The devices I use are an LG HBS-700 headset, an Apple Keyboard and Trackpad. I plugged in an Asus atheros based bluetooth dongle to see if it was the Broadcom driver no longer working, but I have been unable to get that to work either and it has also worked successfully in Ubuntu before. I ran the bluez-hcidump command that was suggested, but it complains about no device being found.
