I suggest you go with the versions that git bisect selects.

I appreciate that it takes you a long time to build and test each
kernel, but hopefully you can reach a stage where the bad commit is
identified.

I think I've seen people report that an old commit was identified
as causing a problem, and I also think that in those cases the
problem was exposed by a later commit.
