Whew! I'm glad someone else is able to see it as well. I was beginning to
wonder if I was just doing something wrong.

Just to be clear though, this error occurs every time I start my VM. It doesn't
even matter if I login to the VM, the warnings have already appeared by the
time the login screen appears.

Anyway, as you said, hopefully your discovery that CPU pinning and -overcommit
cpu-pm get rid of the warnings will help guide the devs to a solution.

Also, I'm feeling a bit under the weather so if I don't respond to requests for
more info for a few days it's because I need to get some rest and get well. But
if anyone needs anything else just let me know and I'll get on it as soon as
possible.
