I wonder what will they tell you.

I have one year premier support.
On previous bios version, ACPI profiles didn't work. I asked them to help me. Support told me that p14s with AMD CPU isn't on the Linux certified list, and they can't help me. (quick and painful )

As I told before.
In Lenovo Product Specifications Reference for p14s gen 4 there is an information that 6E is only supported on Windows 11 (not even Windows 10) so I decided not to ask Lenovo.

Let us know what Lenovo support will tell you.

acpi_osi=! acpi_osi="Windows 2021"

Hi,

"It's ok to hang in here regardless, but this isn't archlinux?
What kernel version is this?"

Sorry I am on Fedora :-/ .
6.6.9-100.fc38.x86_64

"Support told me that p14s with AMD CPU isn't on the Linux certified list"
That's a quick answer ^^.

My laptop is from my company and we also have premier support.
My version is Linux certified, that's why my company choose this model.
It looks like Lenovo engineers were supportive on other posts on their forum, so I posted there: https://forums.lenovo.com/t5/Fedora/Wif … =1#6219694

I have some work to do and some logs to share.

Best regards,

What specifically did you refer to w/ "Kernel driver build is from 2022/12/22"?
6.6.9 is from (very) late 2023

wrt 860lacov mentioning "only supported on Windows 11 (not even Windows 10)", try to lie to the firmware (post #27)

fw_build_timestamp 2022-12-22

That's not the kernel

Tiduster · 2024-01-12 10:56:30

Yeah I know
I said "Kernel driver build", I imagine it's not the right term ^^.

Is it the "Kernel wifi module build date" ? (Genuinely interested)

It's the build date of the firmware, did you try to spoof the acpi_osi? (It tells the BIOS that this is totally windows 11)

Tiduster · 2024-01-17 22:21:46

Hi !

did you try to spoof the acpi_osi

Not yet ! But I will look about it.

I tested on a live USB Ubuntu as requested by Lenovo support.
The laptop see the 6GHz Wifi this time, but I am enable to connect.

I sent every log to Lenovo Engineers.

Best regards,

I used this : https://aopc.dev/t/set-kernel-to-trick- … rsion.175/ to dump some stuff.
I see no mention of Windows 11 in the file.
Only one Windows 10, and lot's of old Windows.

seth · 2024-01-18 21:57:23

Adding https://bbs.archlinux.org/viewtopic.php … 5#p2142285 to the https://wiki.archlinux.org/title/Kernel_parameters will feign Windows 11

860lacov · 2024-03-05 19:43:13

Ok.
Little update.
I've checked just now and my laptop can connect to the 6GHz network.
Didn't do anything except regular system updates.

My currend default config is

$ cat /etc/NetworkManager/conf.d/wifi_rand_mac.conf 
[device-mac-randomization]
# "yes" is already the default for scanning
wifi.scan-rand-mac-address=yes

[connection-mac-randomization]
# Randomize MAC for every ethernet connection
#ethernet.cloned-mac-address=random
# Generate a random MAC for each WiFi and associate the two permanently.
wifi.cloned-mac-address=random

But for my 5GHz network I have stable setting.

Arch Linux
