Thanks for the bug report.
Your kernel log seems to show Bluetooth commands repeatedly failing to transmit:
[337184.522407] Bluetooth: hci0: command 0x0406 tx timeout [337887.553831] Bluetooth: hci0: command 0x0c1a tx timeout [337889.565670] Bluetooth: hci0: command 0x0c3a tx timeout [337891.581728] Bluetooth: hci0: command 0x0c1a tx timeout [337913.213192] Bluetooth: hci0: command 0x1405 tx timeout [337915.229228] Bluetooth: hci0: command 0x1403 tx timeout
So that's either a kernel bug or a hardware fault. BlueZ is not really relevant here.
