我无法在装有 rt8822be 驱动程序的 Fedora 29 上使用蓝牙，主板是 Asus z370e ROG Strix。蓝牙无法启动，如下面的日志所示。我非常感谢任何帮助，因为我的 google-fu 到目前为止无法解决这个问题。
以下是 journalctl -r -u bluetooth 的一些最新输出行

我一直在互联网上搜索与“无法设置挂载命名空间”有关的错误，但我没有看到很多关于它的问题。
以下是 sudo rfkill list all 的一些输出
0: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
以下是运行 sudo hciconfig hci0 的输出
