You can easily get a diff from the git tree, ie:

$ git clone https://git.FreeBSD.org/src.git
$ cd src
$ git diff 0bbbd845fd32ef07707c03d1dc4e4b27f6ebef83..fc952ac2212b121aa6eefc273f5960ec3e0a466d sys

Note the two commit hashes: one is HEAD from releng/13.1 and the
other is from stable/13.  I've added the 'sys' at the end to limit the
diff to changes to the sys/ folder (so kernel only).

In any case, I think such diff is too big to be able to spot any
changes that could cause issues by code inspection.

If you can do the bisection and provide the info from the debug key
(plus the kernel debug symbols) that's likely to be quite useful.

Thanks, Roger.
