Don't worry: If your problem is immediately obvious after booting this should
be not too bad. You can also use the versions you build manually to "seed" the
git bisection process. That way you reduce the number of bisection steps a bit.

If you encounter non-bootable kernels please use "git bisect skip" - this is
important! DO NOT mark as "good"/"bad" in these cases.

I think the "drm-next" thing was mandated by Linus so there is not much which
can be done at this point. But anyway if you have an easily reproducible
problem bisection is not too bad.
