Bug Description

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 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).

Please test this package and see if it fixes the issue.


Note that I incidentally also updated the 8260 firmware (one of the commits fixed a problem with both), so if you have any hardware with 8260 bluetooth some testing on that would be appreciated as well. Thanks!

I tested the package on a new system that hadn't gotten the new firmware installed yet. Bluetooth works after installing the test package.

I can second that.

I have a Gigabyte GC-WB867D-I card. The bluetooth was not working before the installation of linux-firmware_1.157.11~pre201704282144_all.deb and it starts to work after the installation.

I'm also affected by this Bug. I confirm the Test-Package above solves the Problem.

Hello David, or anyone else affected,

Accepted linux-firmware into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/1.157.11 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

The fix is difficult to test directly, but David verified a test version of linux-firmware in comment #2. I've compared the contents of that package to the 1.157.11 in -proposed and found that aside from the version they are identical, so this should be sufficient to verify the -proposed package.

The verification of the Stable Release Update for linux-firmware has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
