Bug description:
  [Impact]
  Encounter "hci0: Failed to read MSFT supported features (-110)" while doing 
reboot stress test.

  [Fix]
  Intel provides 2 commits the fix this issue which is included in the 
linux-next now.

  04c41b875f5b Bluetooth: btintel_pcie: Add recovery mechanism
  f4c8e876ef6b Bluetooth: btintel_pcie: Add handshake between driver and 
firmware

  [Test]
  Reboot stress test on the machine with PCIe BT[8086:a876], the BT should work 
during 100+ reboots.

  [Where problems could occur]
  The 2 patches affect the boot process and the handshake between driver and 
firmware, so if it leads to any regression you could spot it easily after boot 
up. And another patch adds a recovery mechanism to recover controller if 
firmware download fails. So, it should be robust enough to overcome the boot 
regression.
