Intel Wi-Fi 7 BE200 320MHz, kernel warning and system freeze

[MaskRay]

When I run `sudo iwctl station wlan0 connect wifiname` for the first time during a boot, iwctl would error

```
No matching method found
Failed to retrieve IWD dbus objects, quitting...
```

Running it for the second time would succeed and I can then `dhcpcd wlan0`. journalctl demonstrates the relevant kernel warnings for the first iwctl run.

journalctl -b log

I suspect that this is also related to the intermittent system freeze I am experiencing (https://bbs.archlinux.org/viewtopic.php?pid=2251387 ). Freezes have occurred with at least the following Arch Linux kernel configurations:

* core/linux 6.15.6.arch1-1 w/o max_cstate
* core/linux 6.15.6.arch1-1 intel_idle.max_cstate=2
* core/linux-lts 6.12.37-1 w/o max_cstate
* core/linux-lts 6.12.37-1 intel_idle.max_cstate=1

On occasion, a freeze would occur within the first 30 minutes of booting.
wifi/audio/webcam are working. I've gathered full journalctl logs related to freezes

Hello MaskRay,

Thank you for posting in Intel Communities.

I will look into this internally and provide an update as soon as it's available.

Hello MaskRay,

To further investigate this issue, please help share these following details below:

1. When did the issue begin, and was everything functioning properly before?
2. Is this the original adapter that was pre-installed in your system, or have you recently changed or installed a new adapter?
3. Are you using a laptop or a desktop system?
4. Have you upgraded to the latest stable kernel available for testing?
5. Kindly provide the full system specifications (SSU logs for Linux) by downloading the Intel® System Support Utility for the Linux* Operating System. For detailed instructions, refer to our article in the Help Guide for the Intel® System Support Utility.
6. What other troubleshooting steps have you already attempted?

I hope to hear from you soon.

Best regards,

Thank you for the reply!

This problem appeared since I received this laptop Linux (~2 weeks ago).
No hardware components have been replaced since then.

I'm using the laptop with an external monitor, connected through its Thunderbolt 4 port (USB-C compatible).

> Have you upgraded to the latest stable kernel available for testing?

I suspect this is a regression between kernel 6.11 and 6.15.
I observed random system freeze with Arch Linux 6.15.6-arch1-1.

On this laptop, I've also installed Ubuntu 24.04 LTS.
The WiFi functions correctly, and I experience no system freezes when using the older kernel, /boot/vmlinuz-6.11.0-29-generic.

However, booting with the newer /boot/vmlinuz-6.14.0-24-generic kernel consistently leads to a system freeze, often within five minutes of startup.

> Kindly provide the full system specifications (SSU logs for Linux) by downloading the Intel® System Support Utility for the Linux* Operating System. For detailed instructions, refer to our article in the Help Guide for the Intel® System Support Utility.

The "download" link on https://www.intel.com/content/www/us/en/download/18895/intel-system-support-utility-for-the-linux-operating-system.html has no response (in both Chrome and Firefox).
However, I found the release note link
https://downloadmirror.intel.com/26735/releasenotes_3.0.0.2.txt

and guessed the correct URI
https://downloadmirror.intel.com/26735/ssu_3.0.0.2_tar.gz

Attached the report.

> What other troubleshooting steps have you already attempted?

I started a thread "Random freeze, Intel Core Ultra 7 255H, Intel Wi-Fi 7 BE200" on https://bbs.archlinux.org/viewtopic.php?id=306935 

The kernel parameter intel_idle.max_cstate seems unrelated.

Hello MaskRay,

In the forum, you mentioned that the Wi-Fi works properly and there are no system freezes when using the older kernel via Ubuntu 2~24.04, Kernel v6.11, which is supported by pre-installation with additional purchase from the PC hardware link OS.

However, you're experiencing random system freezes with Arch Linux 6.15.6-arch1-1 between kernel versions 6.11 and 6.15.

According to the logs you provided, the system successfully detects BE200 with the latest kernel and firmware, although Arch Linux is not found via the PC OEM.

If you're a corporate user, please let me know how many hardware impacts and projects are involved.

I'm sharing the Linux Driver link here: Intel® Wireless Wi-Fi Drivers for Linux*

Please note that Linux* OS, software, and hardware not officially endorsed by your PC may affect performance and stability. We recommend consulting with the PC manufacturer or Linux* OS distributor to ensure compatibility and functionality with Intel wireless products.

The message "Failed to retrieve IWD dbus objects, quitting..." suggests enabling the automatic startup of the iwd service.

Hi JeanetteC,

I'm using this laptop for personal use, not as a corporate user.

> According to the logs you provided, the system successfully detects BE200 with the latest kernel and firmware, although Arch Linux is not found via the PC OEM.

Correct, I've been running Arch Linux with the core/linux-lts 6.12.41-1 kernel for the past few days, and it's been stable with no freezes.
However, after testing kernel 6.15.9.arch1-1, I noticed a freeze about two hours after booting. The "[ cut here ]" stanza is included below.

In journalctl logs from system freezes, I find "[ cut here ]" stanzas, which is absent in logs from stable boots.

I suspect this is a regression between kernel 6.12.41 (stable) and 6.15.9 (unstable).

The https://www.intel.com/content/www/us/en/download/824804/intel-wireless-wi-fi-drivers-for-linux.html link is for kernel 6.16 . I'll test it once Arch Linux's core/linux upgrades to 6.16.

Hello MaskRay,

I will investigate this further and provide an update once available

Hello MaskRay,

As per further checking on this issue, this is more related to PC OEM support of Linux OS and kernel version. It is highly recommended to reach out with OEM PC for supported Linux OS and kernel version.

Upon further examination, this issue appears to be related to the PC OEM support for Linux OS and kernel version. It is strongly advised to contact your OEM PC for information on supported Linux OS and kernel versions.

I will go ahead and close this thread. Should you need assistance in the future, please submit a new question as this thread will no longer be monitored.

Sincerely,

JeanetteC.
