Bluetoothサービスを再起動できません。

Bluetoothを再起動できません。私は試した:

• sudo service restart bluetooth
• sudo service stop bluetooth
• systemctl stop bluetooth
• sudo kill -9 <bluetoothd-pid>

しかし、systemctl status bluetoothそれでもそれを返します。

ps auxでは、まだ実行していることがわかりますbletoothd。

 ps aux | grep bluetoothd

dmesg私が見ることができるもの：

[ 4944.030004] Bluetooth: hci0: command 0x0406 tx timeout

これを試しましたが、sudo strace -p1728mi端末が停止して閉じることができませんでした。

~$ sudo strace -p1728
