Title:
  syslog flooded with "hci_scodata_packet: hci0 SCO packet for unknown
  connection handle"

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I am experiencing unstable bluetooth connections between a USB
  bluetooth dongle and headset.  I get a ton of lines like

  Dec  1 04:09:51 localhost kernel: [  264.372205] hci_scodata_packet:
  hci0 SCO packet for unknown connection handle 65261

  in syslog.  The bluetooth connection also usually breaks down about 10
  seconds into a Skype call.  I cannot know if the two phenomena are
  actually related.

  Dec  1 04:09:52 localhost kernel: [  264.392198] hci_scodata_packet: hci0 SCO packet for unknown connection handle 65072
  Dec  1 04:09:52 localhost kernel: [  264.402199] hci_scodata_packet: hci0 SCO packet for unknown connection handle 65493
  Dec  1 04:10:26 localhost bluetoothd[1756]: Audio connection got disconnected
  Dec  1 04:10:26 localhost pulseaudio[1936]: ratelimit.c: 4802 events suppressed
  Dec  1 04:10:35 localhost pulseaudio[1936]: ratelimit.c: 428 events suppressed

  I believe this is a Ubuntu-induced regression, I was unable to
  reproduce the problem with a mainline kernel today.

  confirmed affected: vmlinuz-2.6.32-35-generic (latest lucid kernel)
  confirmed affected: vmlinuz-3.0.0-13-generic
  apparently unaffected: vmlinuz-3.2.0-999-generic from today (or rather Nov 30th)

  FWIW, the mainline kernel seems to have a stable bluetooth connection
  but syslog gets flooded there as well.
