Comments/Problems:

During loading network modules, it hangs and just blinks CapLk LED...
Ubuntu 24.10 live works fine.

Kernel panic ? If so, I guess you could not grab /var/log/syslog or run
dmesg.
Can you switch to tty4 before (if normal install) or right after (if
expert install) entering "Detect network hardware" ?

This reminds me of #1032140 with MediaTek MT7921 wireless controller.

check-missing-firmware fails will attempting to reload kernel module on
MT7922 WiFi card).

 Thank you, I've switched to tty4 and got some messages as the image

 and below lines seem to be suspicious.

 ath12k_pci 0000:c2:00.0: firmware failed to load ath12k/WCN7850/hw2.0/firmware-2.bin (-2)
 (snip)
 ath12k_pci 0000:c2:00.0: firmware failed to load ath12k/WCN7850/hw2.0/amss.bin (-2)


 amss.bin is included in firmware-atheros

firmware-atheros: /usr/lib/firmware/ath12k/WCN7850/hw2.0/amss.bin
firmware-atheros: /usr/lib/firmware/ath12k/WCN7850/hw2.0/board-2.bin
firmware-atheros: /usr/lib/firmware/ath12k/WCN7850/hw2.0/m3.bin

 and firmware-atheros_20241210-1_all.deb in d-i has those.

$ dpkg-deb --contents firmware-atheros_20241210-1_all.deb |grep ath12k
drwxr-xr-x root/root         0 2024-12-20 06:13 ./usr/lib/firmware/ath12k/

 Upstream repo also does not have firmware-2.bin
https://git.codelinaro.org/clo/ath-firmware/ath12k-firmware


 Then I did is copying /usr/lib/firmware/ath12k/* before hardware detection
 , ln -s board-2.bin firmware-2.bin and it works without hang up! :)
 However, I cannot specify WLAN setting (SSID, password).

No more messages ?

Missing firmware messages are expected. But I expected more kernel
messages if there is a kernel panic or other serious error. I guess the
syslog process which writes to tty4 is already dead when that happens.

You can try to switch to tty2, run

echo "7 4 1 7" > /proc/sys/kernel/printk

and watch kernel messages in tty2.

Why not ?

My experience matches that of Hideki Yamane, also on a fresh Thinkpad
T14s Gen6 AMD. On Mon, 20 Jan 2025 11:00:44 +0900 Hideki Yamane

There is a firmware-2.bin in the QCN9274/hw2.0 folders, but I guess they
are for another chip?
QCN9274 doesn't seem to be present in the current package in the trixie repo, just WCN7850.

can confirm this works and it seems that the symlink persisted after
installation so the system also had working wifi. > However, I cannot
specify WLAN setting (SSID, password). If I was able to figure out
wpa_supplicant during setup I probably could've gotten it working, but I
opted to not select NTP and just install from the Debian testing DVD1.
Kind regards, Nick
