# first bad commit: [d61746b2e71bf612fb397b00242de5df5ba7f29a] ip_tunnel: Don't allow to add the same tunnel multiple times.
Built and tested all the commits, but none of them worked.
It seems I'm unable to narrow down the commit.
I can assure (because I have tested this twice) the last bad kernel is
3.17.0-rc7-utopic (http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v3.17-rc7- utopic/)
and the first good one
3.17.0-utopic (http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v3.17-utopic/)
I did all the steps to spot the good commit.
Here is the bisect log from git:
