Title:
  Regression in Ubuntu 22.04 kernel 6.8.0 for module ath9k

Status in linux package in Ubuntu:
  Incomplete

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
