I tried again from fresh git clone. First kernel build works fine and give me a "good" bisect.
But second compilation give many errors. What is wrong ? Below the steps : meloli@Asus-A17:~/GITBISECT$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git ... meloli@Asus-A17:~/GITBISECT$ cd linux meloli@Asus-A17:~/GITBISECT/linux$ git bisect start meloli@Asus-A17:~/GITBISECT/linux$ git bisect good v5.8-rc7 meloli@Asus-A17:~/GITBISECT/linux$ git bisect bad v5.9-rc1 Bissection : 7733 révisions à tester après ceci (à peu près 13 étapes) [8186749621ed6b8fc42644c399e8c755a2b6f630] Merge tag 'drm-next-2020-08-06' of git://anongit.freedesktop.org/drm/drm meloli@Asus-A17:~/GITBISECT/linux$ make localmodconfig ---> Some questions here...
