From the logs:

That's not anywhere near close to modeset code, and even further away from the fbdev stuff changed by the supposed bisect. I suspect in all the skipped commits the bisect got derailed somewhere. Please double-check whether the parent of the first bad commit works (and perhaps also double-check the bad commit again). I recommend compiling with CONFIG_LOCALVERFSION_AUTIO and checking that you have the right git version with uname -r to make really sure.
