Title:
Regression in Ubuntu 22.04 kernel 6.8.0 for module ath9k
Status in linux package in Ubuntu:
Confirmed
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
