Created attachment 306659 [details] 6.6 dmesg, broken wifi Booting with debugfs=off breaks initialisation of Atheros AR9287. Was working previously with 6.1 kernel series. 6.6-6.10 kernels are broken (if debugfs is re-enabled, it DOES work correctly)
Created attachment 306660 [details] 6.6 dmesg, working wifi (debugfs on)
It breaks somewhere between 6.5<->6.6, I can possibly do a bisect if necessary, but it will take some time.
Thank you for the report! Could you please try reverting this commit and see if it fixes the issue? 6edb4ba6fb5b ("wifi: ath9k: fix parameter check in ath9k_init_debug()")

Can confirm that the above patch fixes it, tested on top of 6.6.44. You can add `Tested-by: Daniel Tobias <dan.g.tob@gmail.com>` if you'd like, it should maybe also be tagged for stable >=6.6. Thanks for the quick response!
Confirmed fixed with the latest batch of stable patches (6.6.54)
