![蓝牙故障,无法重启](https://linux22.com/image/1203868/%E8%93%9D%E7%89%99%E6%95%85%E9%9A%9C%EF%BC%8C%E6%97%A0%E6%B3%95%E9%87%8D%E5%90%AF.png)
这是我的故事:我想启动 Windows,但我忘了在 grub 上选择,所以它进入了 Ubuntu。我自然而然地重新启动(没有登录 Ubuntu),但它停止了,如下所示:
我只好强制关机并再次尝试,结果问题依旧,错误信息如下:
[12.771190] Bluetooth: hci0 sending Intel patch command(0xfc8e) failed (-110)
[12.771242] Bluetooth: hci0 sending frame failed(-19)
[14.786774] Bluetooth: Exiting manufacturer mode failed(-110)
我的平台是 Ubuntu 16.04 LTS,内核是 4.10.0-42-generic。但奇怪的是,我登录 Ubuntu 后重启工作正常。以下是我的设备和显卡驱动程序的信息:
