Description Mihai Lazarescu 2013-06-20 11:20:04 UTC
Created attachment 763429 [details]
Sample of Bluetooth error messages flooding the logs.

Description of problem:

    After pairing a VH410 Bluetooth headset are generated
    large logs of messages like:

      Bluetooth: hci0 SCO packet for unknown connection handle (16-bit uint)

    (see attached sample).  Sometimes the headset won't pair,
    logging this message:

        Bluetooth: hci0 ACL packet for unknown connection handle 21

    The Bluetooth adapter is the Atheros AR9485 embedded in the ASUS
    UX31E laptops:

        usb 1-1.8: New USB device strings: Mfr=1, Product=2, SerialNumber=3
        usb 1-1.8: Product: Bluetooth USB Host Controller
        usb 1-1.8: Manufacturer: Atheros Communications
        usb 1-1.8: SerialNumber: Alaska Day 2006

Version-Release number of selected component (if applicable):

    kernel-3.9.6-200.fc18.x86_64
    bluez-4.101-6.fc18.x86_64

How reproducible:

    Always.

Steps to Reproduce:

    1. Pair the VH410 Bluetooth headset.
    2. Start an audio I/O stream (e.g., Skype)

Actual results:

    Many messages logged and gaps in audio (both in and out).

Expected results:

    No audio gaps and/or log flood.
