4.4 and bluetooth ...on a Pi2 ??

[DRONE7]

Having odd problems with power dropping on a Pi2 and 4.4 release.....
looking in logs I find....
[  574.011229] Bluetooth: HCI device and connection manager initialized
[  574.011262] Bluetooth: HCI socket layer initialized
[  574.011275] Bluetooth: L2CAP socket layer initialized
[  574.011315] Bluetooth: SCO socket layer initialized

How...what...this is a Pi2... no bluetooth hardware either internal or externally so why is it starting bluetooth services..?

I've never and never will use bluetooth so how can I blacklist/prevent these services.....

Those look harmless to me.

Bluetooth never started (OFF in Audio config), Pi-2B

Code:

pi@rp4:~ $ hciconfig
pi@rp4:~ $ sudo ls /var/lib/bluetooth
ls: cannot access '/var/lib/bluetooth': No such file or directory

Bluetooth running (ON in Audio config), Pi-Zero W

Code:

pi@rp2:~ $ hciconfig
hci0:   Type: Primary  Bus: UART
       BD Address: B8:27:EB:83:68:F2  ACL MTU: 1021:8  SCO MTU: 64:1

       TX bytes:2444 acl:0 sco:0 commands:50 errors:0

pi@rp2:~ $ sudo ls /var/lib/bluetooth/
