Intel WiFi AX200 [8086:08b1] subsystem [8086:4070] firmware loading error resulting in no wifi

[Ari]

Ubuntu 19.10 - stock kernel - Intel AX200 PCI card in a desktop PC

uname -a
Linux nahuatl 5.3.0-18-generic #19-Ubuntu SMP Tue Oct 8 20:14:06 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

The card is detected OK as dmesg shows, however the card's firmware fails immediately after loading (see dmesg output below) and wifi doesn't work at all. Big disappointment since the AX200 chip was supposed to be supported on 19.10.

Ubuntu includes two ax200 firmware versions, version 48 loads by default in my system (and fails). I tried version 46 (by renaming the version 48 file) and it failed in the exact same manner

$ ls /lib/firmware/iwlwifi-cc-*
/lib/firmware/iwlwifi-cc-a0-46.ucode /lib/firmware/iwlwifi-cc-a0-48.ucode

The card's Bluetooth functionality is also detected and it works fine. It's just the wifi FW loading what seems broken in ubuntu's 5.3 kernel.

$ rfkill list
0: hci0: Bluetooth
 Soft blocked: yes
 Hard blocked: no

I have a few different models of newer intel based wifi cards on a minipcie splitter/carrier board https://www.alftel.com/pages/product-airbud-pcie

When the hardware is detected during boot, all the intels on the carrier board fail to load/run their ucode. This is happening on a unit I have dedicated for testing, so I am available for any/all requested testing. Here is what it looks like:

[Ari (ari-reads)]

The issue could be in:

linux-modules-extra-5.3.0-18-generic

(iwlwifi module) rather than in intel's firmware

[You-Sheng Yang (vicamo)]

Hi, could you also try mainline kernel https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4-rc3/ as well as backport-iwlwifi dkms from https://launchpad.net/~vicamo/+archive/ubuntu/backport-iwlwifi-dkms ? The firmware blobs in Eoan are already latest openly available ones.

[Ari (ari-reads)]

@vicamo I tested various combinations, here's the dmesg output:

stock 5.3 kernel + iwlwifi backport: https://paste.ubuntu.com/p/j6WDwqDJcd/

mainline 5.4rc3: https://paste.ubuntu.com/p/VnY6vZvqnC/

mainline 5.4rc3 + backported iwlwifi (there was an error inthe install, see notes in log): https://paste.ubuntu.com/p/WwpmGmPdvh/

Unfortunately no luck - in all cases the firmware errors out immediately after loading.
I noticed the 'trigger' is different with the backported iwlwifi.

FWIW I've seen some old reports of people getting AX200 to work on ubuntu 19.04 using 'mainline kernels' from June/July this year, and also 19.10 some ppl using the chipset on 19.10 daily builds prior to launch - this is why I decided to upgrade SW + change wifi card.

I also notice that the mainline iwlwifi module looks for firmware 50, then 49, and finally loads 48 which is the one that ubuntu ships. The one in the kernel tree is also 48, I wonder if intel keeps a "-next" tree of some sort somewhere where versions 49/50 could be present.

I found these kernel bug reports:

https://bugzilla.kernel.org/show_bug.cgi?id=205123

https://bugzilla.kernel.org/show_bug.cgi?id=204821

They both refer to the use of PCI slot adapters triggering the problem, which do not apply on my case. Motherboard: ASUS Maximus Gene Viii

[ari.reads (ari.reads-linux-kernel-bugs)]

Where you able to work around this error?
I'm seeing the same sysassert, with a single ax200 and no adaptor.

[ 8.812119] iwlwifi 0000:01:00.0: 0x201000A3 | ADVANCED_SYSASSERT

On occassion I've seen sysassert 0x222. In another bug they mention 0x222 could be due to pci timing issues. However I'm using this card in the same slot that used to host another intel wifi card, 7260, for years without a problem.

[Ari (ari-reads)]

Based on a few references and the issue in my system, it seems ax200 has issues with (at least) specific PCIE slot types X16, again at least with certain motherboards.X1/X4/X8 slots seem to work ok consistently. Hopefully this is fixable via firmware, so will retest once Intel releases the next few version

[sidhayn (sidhayn-linux-kernel-bugs)]

I bought a single mpcie->ngff adapter and tested that with a single ax200 and still the same failure. other devices work, intel ax200 does not.

[sidhayn (sidhayn-linux-kernel-bugs)]

I'm going to let the assignee mark this if they agree, but this is probably a dupe of https://bugzilla.kernel.org/show_bug.cgi?id=204821

[You-Sheng Yang (vicamo)]

Hi, could you also attach output of `sudo lspci -vvnk -s 01:00.0`?

[Zero_Chaos (sidhayn)]

I'm not on ubuntu but I'm the same kernel with the same kernel bug and same hardware. Hope this helps anyway :-)

[Ari (ari-reads)]

For reference, here is the output, but with an old intel wifi card 7260 that works perfectly well and is installed in the same X16 PCIE slot where the AX200 fails to load its firmware.

The AX200 was supposed to replace the 7260 however due to this problem I've had to roll back the upgrade.

https://paste.ubuntu.com/p/FywHwCJYq5/

FWIW the system CPU is kabylake core i7, with a z170 chipset

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[luca (luca-linux-kernel-bugs)]

This doesn't seem to be related to 204821, but thanks for pointing it out.

We will investigate what is causing this issue.

[Maheshwaran (maheshmaceee)]

Any update on this issue? Dell latitude 7540 still reporting this issue.

Kernel : Linux 5.3.18-050318-generic

[You-Sheng Yang (vicamo)]

@Maheshwaran, if neither latest mainline kernel[1] nor backport-iwlwifi-dkms[2], along with latest linux-firmware[3], work for you, then probably we can only wait for updates to https://bugzilla.kernel.org/show_bug.cgi?id=205123 from Intel.

Some previously suggested that this issue could have something to do with the type of PCIe slot.

In my case (Wifi card: Asus PCE-AX58BT) the Asus support claims that the card will only work in a PCIe x1 slot and will not work in a x4, x8, x16 slot. It should not have anything to do with PCIe gen2 or gen3.
They specifically mentioned that this information came from their Taiwanese colleges. I guess that this information was added to imply that they are closer to the development of that card and have more knowledge.

To me all of this is super strange and does not make sense. PCIe x1 cards should be compatible with x4, x8 and x16.
Since I was stuck with this issue for 5 months I did send the card back and gave up on using Wifi on Linux.

I have no clue what cards other users with this issue have, but I thought I would leave this information here. Maybe it helps in anyway.

[gabemarcano (gabemarcano-linux-kernel-bugs)]

I just got a fenvi FV-AX3000 card, which at its core uses an Intel AX200. I was getting the same log from the kernel as above with RT ucode: -110, until I did some more snooping around.

I originally plugged in the card to one of the x16 slots on my motherboard (Gigabyte Z77X-UD5H motherboard, CPU is an Intel i7-3770k), which according to the user manual for the motherboard, due to my current configuration, should now be operating with x4 lanes (8x lanes for my GPU, x4 lanes for a 1x sound card, and x4 lanes for the 1x AX200). These lanes are managed directly by the CPU as far as I can tell, per CPU and motherboard documentation. It was in this configuration that I got the RT ucode errors, and the card refused to work on Windows as well.

As per comment 7, I happened to have one poorly placed 1x PCI-E slot available (right under the GPU..., blocking some airflow to it). I switched the AX200 card to this 1x slot, which is managed by the motherboard's chipset instead of the CPU, and... the card loaded:

Hi,

I'm having the same issue with this card (integrated into the motherboard) and I dug a bit inside the code.

The code in (iwlmvm/fw.c) waits for an alive notification and then times out.
iwl_mvm_load_ucode_wait_alive will runn iwl_wait_notification which times out with err -110.

I don't know exactly how it works but iwlmvm starts the firmware (which does not error) and then waits for the firmware to ping that it's alive so it can continue with the setup. This alive ping is not being received hence it times out.

[ravenexp (ravenexp-linux-kernel-bugs)]

I've also bought a Fenvi FV-AX3000 card today, based on AX200. It is plugged into the PCIe x16 slot on my Gigabyte H87N-WIFI motherboard.

My kernel is vanilla 5.7.12 with iwlwifi compiled in.
The firmware always crashes at startup with:

> iwlwifi 0000:01:00.0: Failed to start RT ucode: -110
> iwlwifi 0000:01:00.0: Failed to run INIT ucode: -110

Full log attached.

Looking at comment #8, re-plugging the card in an x1 slot could have helped,
but my MB doesn't have any.
The only PCIe slot it has is an x16 intended for the discrete GPU which I don't need anyway.

I guess I may as well throw the card into the garbage bin...
Or is it something that can eventually be fixed on the driver/firmware level?

[pepsov (pepsov-linux-kernel-bugs)]

I can confirm that the AX200 works OK when plugged in a x1 PCIe slot, and does NOT work in a x16 slot. In the later case it generates the before-mentioned

 "NMI_INTERRUPT_UMAC_FATAL"

followed in the logs by

 iwlwifi 0000:01:00.0: Failed to start RT ucode: -110
 iwlwifi 0000:01:00.0: Failed to run INIT ucode: -110

My setup is
* Gigabyte Z97M-DS3H motherboard
* Fenvi FV-AX200 PCIe x1 adapter card with an Intel AX200NGW NGFF M.2 card
* CentOS 7 (stock 3.10.0-1127.19.1.el7 and mainline 5.8.7 kernels tested)

I want to point out that the adapter card works fine in the x16 slot when used with another WiFi module (DELL's DW1820), so the problem clearly lies with the AX200 not negotiating its PCIe configuration with the motherboard/chipset.

is unlikely to be universally applicable to the other AX200 cards.

My WiFi+Bluetooth card Asus PCE-AX3000 Dual Band (which apparently also uses the AX200 chip if we believe the output of lspci) is inserted into the PCIEX16_3 slot of the Asus WS C422 PRO/SE motherboard. The motherboard has no x1 slots. I am sending this very message using the aforementioned PCE-AX3000 card in the aforementioned x16 slot and an up-to-date Debian Bullseye with the kernel linux-image-5.10.0-1-amd64. I can nevertheless complain that I don't get Internet directly when Linux boots but a few minutes later (reason yet unknown).

The card works in Windows, too.

[stephanhoerold (stephanhoerold-linux-kernel-bugs)]

I have recently built a NAS server based on Openmediavault. "uname -a" gives me Debian 5.7.10. My motherboard is an Asus P11C-I and the Wifi PCIe card is an Asus PCE-AX3000 with Intel's AX200 Wifi 6 chip. There's only one PCIe slot available for use. I get the same error as reported above:

I should also note that I went to kernel git to download what I think may be Intel's latest version of the u-code. But that one throws the same error:

I just experienced this issue after rearranging PCIe adapters in my 0M5DCD board based box (Optiplex 390DT guts turned into Frankenputer.) I moved the wifi6 adapter up to the x16 slot, where a renesas USB 3.0 card was working fine.
 The EDUP branded Intel AX200 chipset based AX3000 Wifi 6 PCIe adapter did not show up after logging in. I copied dmesg to find a list of iwlwifi errors. I was able to reproduce this reliably. It occurred with multiple kernels of version 5.10.24. After moving the iwlwifi driven hardware back to a PCIe x1 slot, expected functionality resumed.

and possibly the

I don't know if there's something with the link that makes it slower, or the timeouts are just really small, I guess we'll need to check.

[Eric Ackermann (worldofjarcraft)]

I have the same problem with a M.2 AX200 card installed in a laptop running Ubuntu 20.04, with kernel 5.11.0-40-generic.
I noticed that the WiFi works fine when I force the driver to load the firmware "iwlwifi-cc-a0-48.ucode" by renaming newer versions of this file, and this also worked with previous kernel releases.
After every update of linux-firmware, however, the renamed files are replaced and the WiFi starts crash-looping again.
Thus, I am confident that the issue is specific to the newer firmware releases for the AX200:
- iwlwifi-cc-a0-55.ucode
- iwlwifi-cc-a0-59.ucode
- iwlwifi-cc-a0-63.ucode
Does anyone know what was changed in these firmware revisions?

For reference, here is the error message printed when iwlwifi-cc-a0-55.ucode is loaded. It repeats over and over until I delete the aforementioned firmware file:

Is there an update to this?
Did anybody get the AX200 card working in a x16 slot?

I had no luck with kernel 5.16.12 (bullseye-backports) and firmware-iwlwifi 20210818-1

Thanks.

[invalidhandle (invalidhandle-linux-kernel-bugs)]

Disclaimer: I'm not a hardware programmer so I don't know how to evaluate the code and understand why it is breaking or what differences are between versions.

I got it working on a Lenovo Legion using the iwlwifi-cc-a0-48.ucode firmware. A clean install put it on the -63 version and Intel's website download is a -46 version.

How to try this fix:

sudo caja (or your file organizer), or terminal using sudo mv /lib/firmware/<Applicable .ucode files> /your/desired/archive location

search for iwlwifi and find the iwlwifi.cc-a0<version>.ucode files and move all but the one you want. I moved the -46 and all other iwlwifi-cc-a0 versions out of /lib/firmware and left iwlwifi-cc-a0-48.ucode in /lib/firmware.

//Please note that there are many .ucode files in /lib/firmware. Move only the files iwlwifi-cc-a0[version.ucode] that you are isolating away from firmware loader.

sudo dmesg | grep iwlwifi will show a bunch of failed to load for the firmware that was moved out of /lib/firmware and then a successful load, in this case:

firmware: direct-loading firmware iwlwifi-cc-a0-48.ucode

If you happen to know how to tell the kernel which one to use instead of moving the ucode files out of /lib/firmware and causing all the startup loading errors please share.

I've spent a ridiculous amount of time researching a solution for this so I hope this helps a few people.

[invalidhandle (invalidhandle-linux-kernel-bugs)]

I forgot to specify that the above fix using iwlwifi-cc-a0-48.ucode is working on 5.16.0-12parrot1-amd64. I haven't tested other higher versions of the .ucode yet.

See my https://bugzilla.kernel.org/show_bug.cgi?id=205123#c13 .

[matthias (matthias-linux-kernel-bugs)]

I also have AX200 card with errors as mentioned above, and no wifi interface at startup.

I tried solution from @invalidhandle and it worked:

I left alone iwlwifi-cc-a0-50.ucode.zst (I don't have version 48) in /lib/firmware and rebooted. Then wifi was ok and I could connect to internet.

I tried also with iwlwifi-cc-a0-77.ucode.zst without success (no interface showing up).

I'm using kernel 6.6.2-arch1-1.
