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). ** Attachment added: "intel-microcode-3.20170707.1.tgz" https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1713532/+attachment/4941094/+files/intel-microcode-3.20170707.1.tgz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1713532 Title: Intel-8260 not init'd by intel-microcode=3.20170707.1~ubuntu16.04.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1713532/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
