[Impact]
After installing new package updates as suggested by ubuntu, my WiFi
Card (Qualcomm WCN785x Wi-Fi 7(802.11be) as far as lshw -C network is
concerned) did not connect to the network again after waking the
laptop from idle.
After some research I found this bug report:
https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2077296
It seems that after updating the firmware package after the bugfix for
the mentioned bug got released, the updated file board-2.bin is now
broken for at least T14 Gen5 AMD. In the mentioned bugfix thread, a
person already posted this issue yesterday. However, I am reposting it
here as suggested by Timo in
https://bugs.launchpad.net/ubuntu/+source/linux-
firmware/+bug/2077296/comments/5.
Running sudo dmesg | grep ath12k reveals that the board data could not
be fetched from the updated file:
