Bug Description

Hi:

Recent upgrade of the Linux kernel from 6.5 to 6.8 on Ubuntu 22.04 broke my wifi atheros device functionality. Errors I am getting are pretty much the same error in kernel log. The regression makes my wifi unusable.

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

Device: 04:00.0 Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01)

Reverting back to kernel 6.5 fixes the issue.

Thanks
