Yeah & it is /regression/ tracking which I don't (or rather didn't)
consider this situation to be. I'm generally a little unsure as to when
I should trigger regzbot in general:
- immediately when I find something?
- only if it goes a while with nothing constructive?
- is it okay to use it outside of "this used to work and now doesnt"?

Either way, but I did some more googling and found this reddit thread:
https://www.reddit.com/r/intel/comments/lqb4km/for_people_having_i225v_connection_issues/

That's being reported against windows & I dunno if the dude is using
firmware and driver interchangeably etc. But the disabling power saving
etc sounds oddly like the issue we have here, since that was a proposed
workaround in Ivan's 2022 reddit thread.

Supposedly I am on firmware-version 1082:8770, but /I/ I have no idea
how that corresponds to windows versioning. That may lend some credence
to your assertion about firmware being the source of many issues.

Aye, likely to be a little difficult to do a meaningful bisection for
me at least, since the motherboard I have with the problem is an AM5
one for the new Zen4 stuff. I'm not an x86 person, so not entirely
sure when that support landed. I may do some poking tomorrow..
