I have written up a tutorial on how to avoid kernel oops! issues like this that crash your server or keep it from coming back up.
I put the tutorial on my Discourse site, since that seemed convenient to me. My site has nothing to do with tech, though. So I unlisted the topic but published it to HTML.
Enjoy.
