具有内核4.12.10-041210-通用Intel 8260蓝牙的Ubuntu 16.04.1无法正常工作

我正在使用具有最新BIOS（2017年9月）的Dell Latitude E7270，运行ubuntu 16.04.1。我首先将股票16.04.1内核升级到主线4.11.7-041107-通用，然后再没有问题，然后又升级到了内核4.12.10-041210-generic，Wifi和蓝牙都停止了工作。因此，我使用来安装到最新的固件（不完全知道更新前的固件）。

重新启动后，Wifi再次开始工作，但蓝牙仍处于关闭状态：

因此，看来intel / ibt-11-5.sfi是罪魁祸首，但我找不到任何更新的intel蓝牙固件。

任何想法 ？

编辑：

干净启动后，在终端上运行此命令可修复蓝牙：

sudo modprobe -r btusb
sudo modprobe btusb

这将附加到dmesg：

但是，我需要在每次重启后手动修改modprobe。知道如何解决此问题以使其在启动后立即正常工作吗？
