Oh well. I asked you to make that whole PHI thing go away.

This is a feature which has nothing to do with PHI. It just happens to be

It's all about a feature which enables ring 3 mwait/monitor.

You really try hard to get your crap behind me. Stop sending out half baken
shit every other day without addressing my review comments.

Your trust level approaches negative space.
