It has been largely running fine since installed, aside from that odd 2x cold boot. I am hesitant to upgrade the firmware as there is [still] no really clear procedure and I don't have the spare equipment to remediate if anything goes wrong.

I wonder if Raptor would burn some flash chips and mail them?  Then you could literally swap out the firmware, and swap back if needed...

How do you mean? It's mostly upload the new BMC flash, note the MAC addresses, let it reset itself, reset the MAC addresses to their prior values, and then update the PNOR.

AFIK the hardinfo RPM was dropped from the main repo tree few years ago.

And I did not have much luck with compiling it. I've lodged a ticket at https://github.com/lpereira/hardinfo/issues/539

I got it working :D, the patch for Fedora 32 from me https://github.com/lpereira/hardinfo/pull/540

To be fair, it's been a long time since I checked the information. I just recall seeing a lot of WIP discussion at the time and decided to take the conservative approach.
