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:
  Bluetoothd prevents sleep

Status in bluez package in Ubuntu:
  Invalid

Bug description:
  I've had this problem for a while with various versions of Gnome and Bluez but
  it's most prominent in Ubuntu 10.04 and 10.10 where the daemon will drop into
  uninterruptible sleep mode and refuse to allow the system to sleep. System
  Monitor says its waiting channel "call_rwsem_down_read_failed"

  The logs I can't say give any useful information but I ran

  cat /var/log/* | grep bluetoothd

  into the attached file so any devs might be able to get something out
  of it.

  I'm running Ubuntu 10.10 on a Lenovo T510
  Intel i5 M540
  Intel Corporation 5 Series/3400 Series Chipset
  0a5c:217f Broadcom Corp. Bluetooth Controller

  Description:	Ubuntu 10.10
  Release:	10.10

  bluez:
    Installed: 4.69-0ubuntu2
    Candidate: 4.69-0ubuntu2
    Version table:
   *** 4.69-0ubuntu2 0
          500 http://us.archive.ubuntu.com/ubuntu/ maverick/main amd64 Packages
          100 /var/lib/dpkg/status

  Expect to happen: The computer is supposed to sleep and bluetoothd to
  be suspended or quit on sleep.

  What happened: Bluetoothd goes into Uninterruptible Sleep where it
  refuses to allow the system to sleep. Reboot fixes issue but that
  defeats the purpose of sleeping on a laptop.
