Hi James, I was not able to reproduce this issue so wondering if you
could help reproduce and collect logs for debug. If OK please first
merge the debug patch which is available in patchwork:

https://patchwork.kernel.org/project/linux-wireless/patch/20240411074812.86700-1-quic_bqiang@quicinc.com/

Please also enable full ath11k log:
modprobe ath11k debug_mask=0xffffffff
modprobe ath11k_pci

Once enabled you should see lots of ath11k logs.
