dmesg output for bluetooth
btmon trace More dmesg traces |
||
Could you please add the daemon logs as well as btmon trace? (In reply to Luiz Von Dentz from comment #1) > Could you please add the daemon logs as well as btmon trace? WRT the former do you mean /var/log/daemon.log? Regarding the latter, I guess I'd need to launch btmon and wait for the problem to appear? I've never used it FTR Created attachment 276259 [details]
btmon trace
This is the btmon traces for a session. In the beginning I tried to connect the headset a few times. It was selecting the HSP/HFP profile instead of the A2DP and not allowing me to change it. After some connection/disconnections I managed to connect it with the A2DP profile.
Then I started to play some music, and after a minute or so I got a sudden disconnection.
That's more or less the description of the trace.

More dmesg traces
Some more traces. The NULL pointer dereference looks pretty bad :)

Created attachment 276257 [details] dmesg output for bluetooth Bluetooth stack is very unreliable when trying to make it work with some headsets as the Sony MDR-1000x. I get frequent disconnections which do not involve any user action/interaction. After those bluetooth does not work and it requires a reboot. I'm attaching the output of dmesg after one of those failures.
