However, too many of generated revisions are unbootable so I have to use 'bisect skip' frequently. I started with 4059 revisions to test (roughly 12 steps) and after 15 steps I still have 2902 revisions to test (rougly 12 steps). Is there any way to speed this process up? I tried to do bisection manually but I do not understand git enough to be able to do this efficiently. My current bisect log is below.
