I solve this problem  copying  whole scripts dir from 5.5.14 where this issue was solved. After this  git reset --hard and after this   git bisect good | bad. Prepare with this: git clone -o mainline --no-checkout \ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git linux/ cd linux/ git remote add -t master stable \ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git git checkout --detach v5.4 git bisect start git bisect good v5.4 git bisect bad v5.5 On each iteration I do git reset --hard and copy sctipt direcotry.
