The lock dep warning is still present in 2.6.31-rc7, so it's not your
auto-suspend patch. The dmesg is attached. The warning came right
after I stopped mplayer streaming audio to the bluetooth headset (with
CTRL+c). I'm running an older gnome bluetooth stack from June 14
(from commit 7b1f2782). I haven't tested whether updating the userspace
bits makes the lock dep warning go way.
