Title:
  bluetoothd freezes and cannot be killed

Status in bluez package in Ubuntu:
  Invalid

Bug description:
  On oneiric, usage of bluetooth is quite problematic for me.

  Every now and then, the bluetooth daemon stops working.

  1) The bluetooth applet keeps showing a connection
  2) System log is filled with some
  11400.468174] INFO: task bluetoothd:1941 blocked for more than 120 seconds.
  [11400.468190] bluetoothd      D 0000000000000001     0  1941      1 0x00000000
  3) Trying to restart the bluetooth service is useless
  The bluetoothd daemon cannot be killed, even with kill -9

  hcidump gives

  HCI sniffer - Bluetooth packet analyzer ver 2.1
  device: hci0 snap_len: 1028 filter: 0xffffffffffffffff

  and hangs.

  Bluetooth was (almost) fine in natty.
