iwlwifi: 8260: missing iwlwifi-8000C-{22..30}.ucode firmware

[Edmund Laugasson]

Filed a bug at https://bugzilla.kernel.org/show_bug.cgi?id=196395 but filing it also here as suggested.

Using amd64 version from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12.2/ in Xenial 16.04.2 LTS based Linux Mint 18.2.

Checking firmware files:
$ ls /lib/firmware/ | grep 8000C
iwlwifi-8000C-13.ucode
iwlwifi-8000C-16.ucode
iwlwifi-8000C-21.ucode

Missing modules that were required according logging output below:
iwlwifi-8000C-22.ucode
iwlwifi-8000C-23.ucode
iwlwifi-8000C-24.ucode
iwlwifi-8000C-25.ucode
iwlwifi-8000C-26.ucode
iwlwifi-8000C-27.ucode
iwlwifi-8000C-28.ucode
iwlwifi-8000C-29.ucode
iwlwifi-8000C-30.ucode
....

$ lspci | grep Wireless

Then added some firmware files:

... after that the Intel 8260 started to work and log output:

I really hope that Ubuntu Kernel Team can cooperate with Intel Linux Wireless Team and make it all working again like it was in case of previous (4.11 and older) kernels.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1704799

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Edmund Laugasson (ed-lau)]

Forgot to add that after downloading missing firmware to /lib/firmware/ folder, I used sudo depmod -a command and then reloaded the kernel module (sudo modprobe -r iwlwifi && sudo modprobe iwlwifi).

[Edmund Laugasson (ed-lau)]

Also would like to mention that the main source for firmware is https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release and direct link to firmware modules https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/plain/

[Mario Olivio Flores (mflores3)]

I found I was able to resolved this by upgrading to the latest version of iwlwifi-8000C-27.ucode. In my case, wifi was fine, but my bluetooth was not working.

27.455470.0 => 27.541033.0

Only source I could find: https://github.com/wkennington/linux-firmware/blob/master/iwlwifi-8000C-27.ucode

After backing up my old version and copying the new file and updating permissions/owner.
depmod -a command
sudo modprobe -r iwlwifi && sudo modprobe iwlwifi
sudo /etc/init.d/bluetooth restart

DONE. finally my bluetooth works on 4.11 and 4.12

[Max Bowsher (maxb)]

It is expected that the -22.ucode file is missing because it was deliberately removed per https://lists.ubuntu.com/archives/kernel-team/2017-July/085667.html

The -27.ucode file was added in linux-firmware 1.165 and updated in 1.168

None of the other versions were ever released by Intel according to the table at https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release

Thus, there doesn't actually appear to be any outstanding problem tracked in this bug, so I'll set it to Fix Released.

[Edmund Laugasson (ed-lau)]

Just for comment:
using
64-bit Ubuntu kernel 4.16.2
linux-firmware 1.173

not working...

journalctl -b | grep iwlwifi

...but kernel 4.15.17 with linux-firmware 1.173 is working...

tried to add (both 4.15.17 and 4.16.2):
iwlwifi-8000C-36.ucode
iwlwifi-8265-36.ucode
...from https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/plain/
...did not help... even caused a problem

also
iwlwifi-9000-pu-b0-jf-b0-38.ucode
iwlwifi-9260-th-b0-jf-b0-38.ucode
...did not help...

[Edmund Laugasson (ed-lau)]

somehow I could once with kernel 4.16.2 and linux-firmware 1.173 get it working:

kernel: iwlwifi 0000:04:00.0: loaded firmware version 36.e91976c0.0 op_mode iwlmvm
kernel: iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208

...but could not reproduce it and rest of times could not get working. Tried to purge original linux-firmware and reinstalled, also deleted all manually added firmware packages but still no results.

Currently working with 4.15.17 and linux-firmware 1.173:
kernel: iwlwifi 0000:04:00.0: loaded firmware version 34.0.1 op_mode iwlmvm
kernel: iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208

[Edmund Laugasson (ed-lau)]

... still using 64-bit Linux Mint 18.3 MATE which is based on Ubuntu 18.04 LTS. Updated linux-firmware package manually. Originally Ubuntu 16.04 LTS has linux-firmware 1.157.17
Would be thankful to know, which firmware version works with which kernel version.

[Edmund Laugasson (ed-lau)]

sorry - Linux Mint 18.3 is Ubuntu 16.04 LTS based... Unfortunately cannot edit and fix the comment...

[Seth Forshee (sforshee)]

The linux-firmware package for xenial contains firmware for all supported kernel versions. You are running unsupported kernel versions, so the firmware you need may not be present and you may need to download it manually.

Marking this invalid since the problems only occur with unsupported kernel versions.

[Edmund Laugasson (ed-lau)]

Actually the current bug report was not against Ubuntu 16.04, codename: Xenial Xerus. It is against missing firmware for newer kernels. Actually Ubuntu 18.04 is using already 4.15 kernel. There are even newer to come when time goes on. At that time when tested newer kernels, the Ubuntu 16.04 LTS was out and therefore used. As I described, also the newest linux-firmware package found in Ubuntu 18.04 LTS still missing required firmware.

[Seth Forshee (sforshee)]

But you said yourself that "kernel 4.15.17 with linux-firmware 1.173 is working." 4.15 is currently the only supported kernel version in 18.04. Over time support for kernels for subsequent releases will be added via the linux-hwe packages, and linux-firmware will be updated accordingly, but as of right now there are not any subsequent releases.

The builds from http://kernel.ubuntu.com/~kernel-ppa/mainline/ are only for testing purposes and are not supported. If you wish to run one of those kernels you may encounter problems like missing firmware, but we generally won't be adding firmware specifically to make these work.

However, as it happens we have added some new iwlwifi firmware to the package currently in bionic-proposed (https://launchpad.net/ubuntu/+source/linux-firmware/1.173.1) for other reasons, so this might coincidentally provide a version that will work with 4.16.
