Hi , I upgraded kernel 2.6.30-rc5 which includes below fixes Marcel Holtmann (4): Bluetooth: Move dev_set_name() to a context that can sleep Bluetooth: Fix wrong module refcount when connection setup fails Bluetooth: Don't use hci_acl_connect_cancel() for incoming connections Bluetooth: Don't trigger disconnect timeout for security mode 3 pairing i am using bluez 4.32 .After that i tried a2dp connection with automatic key option which is failed. because Error : Authentication failure is thrown by another end. Is this problem with remote bluetooth dongle ? Do i need to upgrade bluez to latest version? Please help me to reslove the issue.
