I don't know what the constraints are, but if you must build kernels based on my tests, then this is going to take a few days.
On the other hand, if I have a bunch of kernels, I can install them all at once, boot one then boot the next until we find the culprit. That's at most one hour, not counting download time, which for me would be around 15-30 min per kernel, but that can be automated.
Whatever the method, as I said, you build them, I test them.
OK! I'll check that one out this evening.
