If you want to automate it, you could try using op-test (
https://github.com/open-power/op-test-framework ) and specifically,
running with "--run testcases.OpTestFastReboot.OpTestFastReboot", you
can set up a small script to do "git bisect run" by invoking op-test to
flash the skiboot image and try to see if fast reboot works.
