The KP occurs at the point when the "p5.28-mozilla-ca" port dependency has been downloaded and is starting to install - the screen goes black and I'm invited to hit any key to restart. A "Problem Report" is presented once I restart. I've looked at these reports when I hit space and restart, but don't see anything obviously pointing back to MacPorts.

I've tried disabling some accessory software (Little Snitch, Karabiner Elements, TunnelBlick) but I can still KP the system even when those are disabled. And I don't understand what the "p5.28-mozilla-ca" port could be doing. I'm not a MacPorts developer and while I could start peeling the onion on what exactly the port is doing, I'd rather that someone else do that.

Yes, several other users have reported this bug in Big Sur. It is tracked here:

https://trac.macports.org/ticket/61683

A kernel panic is a bug in the operating system. You should report it to the operating system vendor so that they can fix it.

Great, then there's no issue. :)
