Public bug reported:
Bluetooth doesn't work in Ubuntu 16.04 on systems with Intel 8265
wireless modules that haven't yet had firmware loaded onto them. dmesg
reports the following:
Bluetooth: hci0: Direct firmware load for intel/ibt-12-16.sfi failed
with error -2
This could be difficult for many people to reproduce, since installing a
later version of Ubuntu once will load the necessary firmware, which
will persist through reinstalling the operating system. So installing
Ubuntu 17.04 just once, will leave Bluetooth in a working state forever.
I was able to consistently produce the issue on a *brand new* Kabylake
Meerkat 3. With Ubuntu 16.04.2, bluetooth didn't work. I copied the
ibt-12-16.sfi and ibt-12-16.ddc into /lib/firmware/intel and rebooted.
After this point, Bluetooth worked (and continued to work after
reinstalling Ubuntu 16.04.2 and *not* copying the firmware files again).
