1st boot log of the bug occuring

I seem to get this bug an indeterminate amount of time after a boot. It's
happened twice when I'm away. Unfortunately, I don't know how to reproduce it
yet as a result. I thought it was suspend, but that seems to work fine when I
invoke it manually. I'll attach both boot logs. I have the debug kernel options
added and will attach that log when it happens again.
