A git bisect is really only possible in the full kernel tree. But it won't take a lot of steps to get a result, because you already narrowed it down to 4.14-4.15. It might take 10 iterations or so (git will tell you). Due to incremental builds that can be done pretty quickly. As the whole kernel is searched for a change, a reboot is usually needed after each iteration step. There are a couple of howtos on the web regarding git bisect: https://duckduckgo.com/?q=3Dgit+bisect+kernel --=20 Michael --Sig_/mgEmzvzjbh2z+x1l_7N0bJv Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEihRzkKVZOnT2ipsS9TK+HZCNiw4FAlscMhsACgkQ9TK+HZCN iw5tcA//f2OlAyDgMPBGgPDZvWRe5gxe8jI6TAG5WMcWZMdXzx344G5zL6rZHoCp 5BLE9lh3VZZjh4t3HP8mFVhoaDMsoT1osPu0dlaLFnQPjzDHLCRLlbYtAoj9ewSm k30ua+WY52MLaH/Yj8MstAFzVZNh3c9J0JDV3ECq9G0w503wIMAV7Y2S2vFqxw4s FT14gBpKFLU0aJ4DiD6lWVeYnQ3ixBvjSpatMspEkmpWS3YBww6JDL2WU7N4nvnD 4J1PiUqdmPfjTbcRuZg9xBV4TNYlVvaN3JuYe79zrsAqEU8PSIQiqyv0uvxo+62R Od2DCX6HgMnIEMMaPLBjqg9UNx+G1ZTHctk4iMCU9L/Mq5ja59poV7SAwOJ7j1on o5XHqP5VCmpP8u0dkOVUHDK4DIXqyUi3liHVxvDBQ2Eda1hi+GPmzjjjxb5rQnlr nth7yjgJ8kliWWJ+a7t0MhRyh2kPKIiKgRKTFA2vgbcwZ7jHPew7FQXHpTTtRMO0 Qmttm8gua2a0NS5pir6AdsTlHelHtoNOugBFiVjx+i+oaLnC0FpqhVrzlu4jn6RY k1yGTYsBhZM3M9Zwt38b6hY/JSTB9uR5RAYTV5VKew6JhpBcEdWeP4JR888bLam+ 9X0kOXNiFbfV4x/RS8GjAi8eDwWA3hC2oym70LEtrQ217rMTBFA= =EQD5 -----END PGP SIGNATURE----- --Sig_/mgEmzvzjbh2z+x1l_7N0bJv--
