This is reported against an old version of Ubuntu and many things has
changed since then. Because of that we won't fix this issue however if
this behavior repeats on a modern version please fill a bug report
against it and we will take it from there.

Title:
  Kernel panic when a Motorola S305 Stereo headset requests connection

Status in bluez package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: pulseaudio-module-bluetooth

  Recently we found an almost 100% reproducible issue when using
  Motorola S305 stereo headset and Ubuntu 9.10. The Ubuntu system has
  auto-update turned on and keeps up with the latest stable release. See the package list at appendix #1 at the end.

  The procedure to reproduce the issue is:
  1. Pair the S305 headset from Ubuntu using the bluetooth icon in the
  task bar, "Set up new device..."
  2. In the "Bluetooth Preferences" screen, hit "Remove" button to
  remove the paired S305.
  3. Power off and then power on S305.
  4. The S305 will try to connect and get a negative link key reply.
  You'll see the PIN input dialog flash away quickly because after the
  negative reply, the LMP link is detached.
  5. After step 4, the S305 willl request again and this time you'll be
  given the dialog to input the PIN. Put '0000' and you'll see the
  desktop frozen. Keyboard, mouse, network ... everything is down.

  With step 5, I don't expect the audio is correctly setup as there
  should be a couple of more configuration to do. However, the
  unexpected thing is that the system hang up. I've reported the issue
  in linux-bluetooth mail list and would like to see if the issue can be
  caused by some process crash in user space. I managed to find the log
  of Appendix #2. My system still has so the panic backtrace is not
  available , however I attached a picture taken by my mobile.

  For those who are interested, I have the hcidump log and my initial
  analysis here:
