I had a problem with pulseaudio-4 and A2DP so I kept it masked until recently; decided to get everything current. I'm mostly in amd64, but I pulled bluez from ~amd64 in hopes of fixing this issue. If I try the following: $ bluetoothctl [NEW] Controller 00:02:72:35:41:B4 sumblue [default] [NEW] Device 34:DF:2A:09:A5:D0 Velodyne vFree [bluetooth]# power on [CHG] Controller 00:02:72:35:41:B4 Class: 0x0c0104 Changing power on succeeded [CHG] Controller 00:02:72:35:41:B4 Powered: yes [bluetooth]# paired-devices Device 34:DF:2A:09:A5:D0 Velodyne vFree [bluetooth]# connect 34:DF:2A:09:A5:D0 Attempting to connect to 34:DF:2A:09:A5:D0 [CHG] Device 34:DF:2A:09:A5:D0 Connected: yes Connection successful It says successful, but no more commands will run and if I look at the klog, [ 174.634534] input: 34:DF:2A:09:A5:D0 as /devices/virtual/input/input8 [ 176.748020] bluetoothd[2143]: segfault at 0 ip 00007fca1706037b sp 00007fffe876b050 error 4 in bluetoothd[7fca1702a000+d8000] and syslog: Mar 28 15:48:49 [bluetoothd] /org/bluez/hci0/dev_34_DF_2A_09_A5_D0/fd0: fd(22) ready Mar 28 15:48:50 [kernel] [ 174.634534] input: 34:DF:2A:09:A5:D0 as /devices/virtual/input/input8 Mar 28 15:48:52 [kernel] [ 176.748020] bluetoothd[2143]: segfault at 0 ip 00007fca1706037b sp 00007fffe876b050 error 4 in bluetoothd[7fca1702a000+d8000] Mar 28 15:49:25 [dbus] [system] Activating service name='org.freedesktop.NetworkManager' (using servicehelper) Mar 28 15:49:25 [dbus] [system] Activated service 'org.freedesktop.NetworkManager' failed: Launch helper exited with unknown return code 1 If I /etc/init.d/bluetooth restart while leaving bluetoothctl open: [DEL] Controller 00:02:72:35:41:B4 sumblue [default] [NEW] Controller 00:02:72:35:41:B4 sumblue [default] [NEW] Device 34:DF:2A:09:A5:D0 Velodyne vFree [CHG] Controller 00:02:72:35:41:B4 Class: 0x000104 [CHG] Controller 00:02:72:35:41:B4 UUIDs has unsupported type [CHG] Controller 00:02:72:35:41:B4 UUIDs has unsupported type [bluetooth]# quit [DEL] Controller 00:02:72:35:41:B4 sumblue [default] I recompiled my kernel with uinput and tried both vmlinuz-3.13.7-gentoo and vmlinuz-3.12.13-gentoo. I've searched countless forums about this in Gentoo, Ubuntu and Arch and nothing I've found seems to work. I continually get the segfault. This did work with pulseaudio-2.1-r1 and the older net-wireless/bluez-4.101-r8 (was using blueman, but unmerged that since there is no bluez-5 version; pretty much the same as bluetoothctl with GUI so no big deal...similar results with Bluedevil which serves the same purpose) This might be totally unrelated, but gdm never started for me either. I get a blank screen occasionally a screen with a clock I can't interact with. A few months back I just switched to xdm, but I'm wondering of the "Activated service 'org.freedesktop.NetworkManager' failed: Launch helper exited with unknown return code 1" is somehow related (saw things in various forum posts).

Running bluetoothd -d as suggested in https://bugzilla.kernel.org/show_bug.cgi?id=73061#c3 would help. Also, you could probably take a better backtrace: https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces Additionally, you could install abrt to let it catch the backtrace for you (once enough packages are recompiled with debugging symbols)
Created attachment 373936 [details] btmon logs
I tried stopping the bluetooth service and running it manually with -d, but there was no debugging output or new stuff in the system/kernel log that I could see. I ended up getting everything working by removing the bluetooth USE flag from all the gnome packages I use, masking Pulseaudio-5 (going back to Puselaudio-2, bluez-4 and blueman). I know that's a bad fix, but I'm going to keep kicking the can.
Please forward the btmon output to upstream too as they requested it and will surely give them more usefulness than me ;)
btmon logs have been added upstream.
i have a working A2DP experience using bluez-5.15 and pulseaudio-5.0.
