The 6.8.11 is Debian’s current Linux kernel in the suite *unstable/sid*
(*linux-image-6.8.11-amd64* 6.8.11-1).

Thank you. I haven’t found out yet, how to reproduce this. I’ll keep an 
eye on it.

As the commit message says:

There are reports from 2016 to 2021 with similar symptoms. These were 
supposedly fixed with 
`/usr/lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin` [1][2]:

     $ md5sum /usr/lib/firmware/ath10k/QCA6174/hw3.0/board.bin 
/usr/lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin
     cb37c63d9ca28f53fea1ff09ad7c7a82 
/usr/lib/firmware/ath10k/QCA6174/hw3.0/board.bin
     651e921b372848b3928621e6f1d34b01 
/usr/lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin


Kind regards,

Paul
