description |
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). |
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.
