I know that a good kernel can be built with r271273 and
a bad kernel comes from (nearly) top of tree at r274456.

I assume I need to do somthing along the lines

% cd /usr/src/sys
% svn merge -r 274456:272864    (half way point between good and bad)
(build kernel and test)
% cd /usr/src/sys
% svn revert -R .
(assume 272864 builds working kernel)
% svn merge -r 274456:273660   (1/2 point between 272864 and 274456).

There's no instructions on how to install it.

In absolutely worst case yu can check out git tree and bisect that :->

Nope.  Learning how to use git and github is well beyond any interest
I have.

I just sent you a workflow that will take you about 10 minutes to sort out for git.

If you want reply in private and I can send you my phone number to show how if you get stuck.
