Thank you, I've switched to tty4 and got some messages as the image https://photos.google.com/share/AF1QipPpfBNPwubDytT9WHMJpmeQx8s-31Abd7IJWB23f00-NNUZLtmkRDhVQMKGQ1VCLw/photo/AF1QipOFOwU57-BdpsXJH5fyVs-S682M9VjeKbR6MCC2?key=WU9tRDdRUjRnekxWd0dOYVJkMGxhV2oySHJ3ZldB
No more messages ?
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)
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.
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/ drwxr-xr-x root/root 0 2024-12-20 06:13 ./usr/lib/firmware/ath12k/WCN7850/ drwxr-xr-x root/root 0 2024-12-20 06:13 ./usr/lib/firmware/ath12k/WCN7850/hw2.0/ -rw-r--r-- root/root 6000704 2024-12-20 06:13 ./usr/lib/firmware/ath12k/WCN7850/hw2.0/amss.bin -rw-r--r-- root/root 1897968 2024-12-20 06:13 ./usr/lib/firmware/ath12k/WCN7850/hw2.0/board-2.bin -rw-r--r-- root/root 299660 2024-12-20 06:13 ./usr/lib/firmware/ath12k/WCN7850/hw2.0/m3.bin 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).
Why not ?
