--- Comment #34 from Michel Dänzer michel@daenzer.net --- (In reply to George Cheban from comment #31)
Compiled a new kernel v4.1: # git checkout -b v4.1
There is no v4.1 tag yet, this command just created a branch called v4.1 at whichever commit was checked out when you ran it.
# git revert 1a81b94...
That commit has no effect whatsoever on your system.
What to do next?
You need to restart the bisection process, and test longer before running "git bisect good".
