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).
Rinse and repeat.
Use git, it has a built in bisector to shake this sort of thing out:
I won't be drawn into the git debate.
OK, so we don't want to use a tool purposefully built for the problem
you are facing? Doesn't seem like a "git debate" more like hammering in
screws...
