uellue, ok, so this indicates that this isn't a linux (Ubuntu) kernel
regression, but in some other package. Next, could you please return
back to the default kernel, install the firmware from Precise (1.79.18,
or whichever earlier version from that you know worked), and advise if
the bluetooth begins to work?

Title:
  Bluetooth: can't load firmware, may not work correctly

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Bluetooth does not work. The tray icon appears, but none of the functionality is available. Probable cause:
  The firmware for Bus 001 Device 003: ID 0a5c:21e6 Broadcom Corp. BCM20702 Bluetooth 4.0 [ThinkPad] does not load. The message in dmesg is "Bluetooth: can't load firmware, may not work correctly". The problem appeared after upgrading from the previous LTS version (12.04?).
