Dear Maintainer,

Wifi with a USB wifi adapter with AR9271 chip (TP-Link TL-WN722N) works fine
with linux-image-7.2.9+deb14-amd64 but fails to initialize with linux-
image-7.2.11+deb14-amd64 and linux-image-7.2.10+deb14-amd64. Running "modprobe
-r ath9k_htc" always results in a "Kernel Panic, Fatal exception in interrupt",
forcing a hard reboot. Running "sudo update-initramfs -u -k 7.2.11+deb14-amd64"
(and the same with 7.2.10+deb14-amd64) has no effect on this issue after a
reboot. Plugging in the wifi adapter into other USB ports also had no effect.

Hi,
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=90201351a862182bdabfc1ad1c97b1e1b6ed5931

Can you test the kernel with that patch (i.e. the revert) on top
applied and see if this resolves your problem?

If so it might be a duplicate of #1151097 and would merge both bugs
later.

Regards,
Salvatore

I tested 7.2.11 with the patch and it resolved the issue.

Thanks.
