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.

Thanks,
Balaji.P

the 2.6.30-rc6 kernel should contains fixes for this to make pairing
smooth with either Legacy or Simple Pairing.
