I’m about 3/4 certain that it’s between those times, and never at the top of the hour.
Getting the exact panic would unfortunately mean to have to get it down from the shelf where it lives, and plugging it into a monitor to replicate. It doesn’t make it out of low-res text mode when it does.
Most of the time, I’m usually in a rush to get it back up as my family wants lights and Plex to work normally.
If you get a chance to test, I'd recommend changing the time on the device and seeing if that makes a difference, should clue you in on if it's a software or environment issue.

I do my best not to reboot to keep the peace!
