Thanks, Greg - good suggestion regarding `git bisect`. I was able to narrow it down to a change between 5.8 and 5.9, so maybe that's the next logical thing to do. None of the config options added between those releases seemed relevant to the issue, but perhaps one of them is and I just don't realize it.

`git log v5.1..v5.2` will show you the whole log, but that's a lot.

I doubt support for such modern hardware has been dropped in kernel
versions like this. Odds are you just forgot to update a configuration
option.
Try using `git bisect` to track down the offending commit, that will go
much faster.
good luck!
