coreaudiod and launchd are taking up 80% and 40% processor respectively
Just had the exact same issue after restarting. I had previously unloaded a bunch of services.

The bluetooth issue was due to unloading the bluetooth service, but I had a bluetooth mouse plugged in via USB, I guess there was some override in the IO or something. 

Loading the service again fixed the issue.


  sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.blued.plist


The core audio issue seems to have been fixed by loading the video assistant again


  sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.cmio.IIDCVideoAssistant.plist


Hope this helps someone as there shouldn't be the need for a full system restore because of one or two service issues.
