My system uses an Intel Corporation Alder Lake-P PCH CNVi WiFi (rev 01) adapter. Symptoms: The output of nmcli general wifi-hw shows "missing". The output of rfkill list does not show any Wi-Fi devices (only Bluetooth). Ethernet connection works as expected. The Wi-Fi hardware functions correctly when booting into Windows on the same machine, indicating the hardware itself is not the issue. *I use dual boot, but my EFI files between Linux and Windows partitions are split I have tried several troubleshooting steps, including: Ensuring the iwlwifi kernel module is loaded (it was). Checking for firmware-related errors in dmesg (no obvious errors related to missing firmware for this specific adapter were found). Reinstalling the linux-firmware package. Installing the intel-ucode package. Resolution: The issue was fixed by downgrading to linux-lts version 6.12.

I have confirmed that the bug does not occur in version 6.13.8. I used the `linux-6.13.8.arch1-1-x86_64.pkg.tar.zst` package from the Arch Linux archives, and the Wi-Fi worked normally. 2. I have started the `git bisect` process. The initial log is: ``` git bisect start # status: waiting for both good and bad commits # bad: [38fec10eb60d687e30c8c6b5420d86e8149f7557] Linux 6.14 git bisect bad 38fec10eb60d687e30c8c6b5420d86e8149f7557 # status: waiting for good commit(s), bad commit known # good: [ffd294d346d185b70e28b1a28abe367bbfe53c04] Linux 6.13 git bisect good ffd294d346d185b70e28b1a28abe367bbfe53c04 ``` 3. My question now is how to proceed with testing the intermediate commits that `git bisect` will select. Do I need to set up the environment and manually compile the kernel for each `bisect` step in order to test the Wi-Fi? I would appreciate any guidance on this. 4. Forget to mention that my distro is not archlinux, it's cachyOS but Im using the kernel provide from arch linux archives. https://github.com/CachyOS/linux-cachyos/issues/425 Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2112190/comments/2 ------------------------------------------------------------------------ On 2025-03-30T14:40:19+00:00 develop-asunnya wrote: Created attachment 307909 Zip with LOGs from 6.14 and 6.13 - iwlwifi loop I am attaching a `.7z` archive containing 3 log files - One with NetworkManager logs from kernel 6.14 (where the bug occurs). - One with 'iwlwifi' related kernel messages from 6.14. - One with kernel logs from the working 6.13.8 version.

It looks like the handshake failure was also there in 6.13 already, but I don't know why. I couldn't reproduce it here on any device that I could get my hands on (though not the same MAC/RF combination so far). Assuming this patch works and you only get a single "FW reset handshake timeout" and no follow-up errors, you could try the FW debug from https://wireless.docs.kernel.org/en/latest/en/users/drivers/iwlwifi/debugging.html#firmware- debugging and capture the dump and send it to us.
