Dear David, this is different issue. My CPUs are just fine and I can use the laptop without issue. Still the my laptop whines. Downgrading, upgrading to a rolling release, or (gasp) installing windows would be running from the problem. Ideally, a kernel shepherd would teach me to coax my sheep to calm down when being rewoke. It's bleats but does not stink, and all I have figured out to remedy this is to knock it out :-). Killing this bleating lamb is not an option. Cheers,Brian
