[Bug 1713532] Re: Intel-8260 not init'd by intel-microcode=3.20170707.1~ubuntu16.04.0

[yarko]

With no more than intel-microcode (re-) upgraded to
3.20170707.1~ubuntu16.04.0, and booting - now bluetooth works.

I can say this:  with initial dropout of bluetooth, I rebooted I think a total of 3 times:
Once just reboot;  Once complete power-down / power-up.   Then, only downgrading intel-microcode worked.

Just now, I upgraded intel-microcode (simply, ubuntu dist - "sudo apt
install intel-microcode" to bring it current), powered- down/up, and
bluetooth works.

The only other thing I can note:
- I did revert the setting in /etc/bluetooth/main.conf => Autoconf=false (actually, commented out, so default as distributed)
- I booted with a USB keyboard plugged in (also);
- The bluetooth icon has (unusually?) a "lock" icon (upper toolbar, right)

Looking at /var/log/apt/history.log -the only other thing changed / I
tried (before downgrade - but not rebooted after) was an install of
unity-control-center (no doubt from googling around, before I looked at
install history for the root of my problem).

Here is (this time) the logs from this boot.

=> I'll wait for guidance / request from someone here on next steps.

If nothing else, I will do the "normal" next step of apt-upgrading,
which will upgrade my kernel (but I'll wait to hear from anyone here,
first).

Title:
  Intel-8260 not init'd by intel-microcode=3.20170707.1~ubuntu16.04.0

Status in intel-microcode package in Ubuntu:
  New

Bug description:
  I'm running:

  LSB Version:	core-9.20160110ubuntu0.2-amd64:core-9.20160110ubuntu0.2-noarch:printing-9.20160110ubuntu0.2-amd64:printing-9.20160110ubuntu0.2-noarch:security-9.20160110ubuntu0.2-amd64:security-9.20160110ubuntu0.2-noarch
  Distributor ID:	Ubuntu
  Description:	Ubuntu 16.04.3 LTS
  Release:	16.04
  Codename:	xenial

  On a NUC6i5SYH, with 32G RAM, and BIOS 0061

  Recently, the following package update happened:
  intel-microcode=3.20170707.1~ubuntu16.04.0

  Upon reboot, bluetooth was unavailable / uninitialized.
  Poking around w/ various tools, I think the insightful bit came from:
  `service bluetooth status -l` which showed multiple lines of
  `not enough free handles to register service` (see attached image).

  Rolling back to:
  `intel-microcode=3.20151106.1`

  and rebooting restored bluetooth function (I use a bluetooth
  keyboard).

  I did try (and leave) changing /etc/bluetooth/main.conf as follows:
  `Autoenable=true`

  It didn't help under the new intel-micorcode, and seems to have no
  noticable deleterious effect under the old intel-microcode.

  Let me know if there's any other / more information I can provide to
  help.
