** Description changed: + SRU Justification + + Impact: Missing firmware causes Intel 8265 wireless to not work in + 16.04.2 installs on new hardware. + + Fix: Backport upstream linux-firmware commits to add the firmware and + subsequent changes which fix some issues with the firmware. + + Regression Potential: The bug fix commits also fix the same issue in + another Intel bluetooth firmware file. Regressions are possible but not + expected since it's a bug fix update. + + Test Case: This is difficult to test since the bluetooth module only + fails to work if it has never had firmware loaded to it previously. + Three different users have confirmed that the test package fixed the + issue. + + --- + 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 + 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).
