Hi There, I would like to report a bug that I am on Debian 12 (6.1.0-37-amd64), which works good and after upgrading it to Debian 12 (6.1.0-*41*-amd64) the WiFi module, ath10k, stops working. Both lsmod outputs look the same about ath10k; however, dmesg shows more errors on 6.1.0-*41*-amd64, "*wmi unified ready event not received", * no WiFi interface appears.
I'm not sure where I should report this to. Please advise. Thank you. *Logs* *On Debian 12 (6.1.0-37-amd64), working fine.
