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

[Dave Chiluk]

@yarko, Please start by gathering the information @hmh requested.  Those include:
1. output of /proc/cpuinfo
2. /var/log/kern.log

Please provide both of these with both the working and newest microcode.
Also please reverify bluetooth in both cases, as we need to make sure
that the issue wasn't simply resolved with a reboot.

Thank you,

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.
