regression in jammy kernel 5.15 for module ath9k

This change was made by a bot.

Reproduced with the daily live iso to avoid loading out of tree module, installing qemu-system and loading the kvm module triggers the issue as well.

This might be related since it shows ath9k symbols:

I'm running Kernel 5.15.0-28.29 from jammy-proposed now and the connection stability problems seem fixed for me, while one time on boot the UBSAN message is still emmitted.

The "UBSAN: invalid-load in /net/mac80211/status.c:1164:21" is fixed in kernel 5.18 (tested on 5.18-rc1 as newer builds for amd64 fail on the Mainline PPA). I believe it was solved in https://patchwork.kernel.org/project/linux-wireless/patch/iwlwifi.20220202104617.0ff363d4fa56.I45792c0187034a6d0e1c99a7db741996ef7caba3@changeid/

The kernel in jammy-proposed works for me as well. Can confirm that I get the same message as well.

Same issue here,

I've tried updating to kernel to kernel 5.17.2, kernel 5.17.5 and 5.18-rc1 but I experience the same issue .... any help welcome ! Thanks

By the way, I did install it manually following these instructions and packages : https://sypalo.com/how-to-upgrade-ubuntu

Have the bug at Lubuntu 22.04
