Unless it happens with just the ath9k active, this ML is likely not the > correct one. as a quick test I unloaded r8169 and did not see this message, but I also added it in and suspended and no warning message as well. I will keep an eye out for this and see if I can reproduce this. (if so a bisect should not take to long) as for lists I can go and remove linux-wireless -- Justin P.
