Bug Description

wireless connection is unstable with kernel 5.15 in jammy release.

the following line is in my log,

ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x02000020 DMADBG_7=0x00006100

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.

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/
