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. - Evan On Mon, Feb 8, 2021 at 1:52 AM Greg KH <greg@kroah.com> wrote:

Apologies if this comes off as a lazy question, but after a fair bit of searching I've been unable to find a changelog indicating which device drivers / features were dropped from various versions of the kernel. Does such a changelog exist?
`git log v5.1..v5.2` will show you the whole log, but that's a lot.
I'm specifically trying to narrow down why the PCI devices on a server I have work with 5.8 and don't work with 5.9+. The server is circa 2014, so I suppose there's an off chance support for some component got dropped.
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!
