--- Comment #10 from johnbholland@icloud.com ---
Since I recently retired, I have some time to put into this. I have 
built 6.3.12 and 6.4.0-rc1 from kernel.org sources and tested, the 
6.3.12 works and the 6.4.0-rc1 does not (in terms of the bluetooth 
issue). Looking at the git log of 6.4.0 there was a lot of bluetooth 
related activity. I've chosen a commit from before that and am trying to 
build that and test it. If it boots and the bluetooth works, I guess 
6.4.0-rc1 and that starting point could be initial points to use in 
bisecting? This is somewhat new territory for me but so far it's been 
pretty straightforward.  The kernel builds take a long time on this 
macbook pro from 2014.
