表现在开机的时候有 hci0 reading feature failed 之类的报错。
关闭蓝牙的时候有 resetting during shutdown failure
有时候有 hci0 operation 0x0804 tx timeout 报错。而且关闭蓝牙会使得整个系统 freeze 一会儿（7-8 秒左右）。
从 dmesg 输出理撷取一些 error
Bluetooth: hci0: Malformed MSFT vendor event: 0x02
Bluetooth: hci0: Reading supported features failed (-16)
Bluetooth: hci0: sending frame failed (-19)
Bluetooth: hci0: HCI reset during shutdown failed
Bluetooth: hci0: command 0x0c03 tx timeout
Bluetooth: hci0: HCI reset during shutdown failed
dmesg 完整输出如下
