I am having this issue since a while, with El Capitan, didnt have any problem.
On Energy Saver window, everything is deselected except put hard disks to sleep when possible. I don't have any USB device attached except a Waco tablet and disconnecting it doesn't solve the issue.
Any ideas?
Cheers,
Fatih
