Those look like kernel messages. A Google search leads me to <https://bugzilla.kernel.org/show_bug.cgi?id=82761> which reports a similar (but worse) experience. You can start there, or try your own luck with Google searches. If you're experiencing an actual problem, you might try contacting the Linux kernel mailing list. If it's just a few lines of text with no other symptoms, personally I'd just ignore it.
