Here's some sample logs with the correct times, apologies for not providing the
timestamps.

I'll reach out to Fedora's Discourse/Universal Blue Discourse.

Here's the full dmesg log via `journalctl -o short-precise -k -b -3`:

GitHub Gist due to the large size, if you rather have me hosting it on a FOSS
alternative, let me know, I can upload it to gitlab.gnome.org)

Let me check and circle back.
