bisect log

After trying to printk around this commit, I noticed some strange behavior,
just adding debug statements making the stripe disappear. I suspected some side
effects in the compilation process.

I've redone the bisect using mrproper instead of make clean between builds,
copying my .config each time. I use make -j20 too.

Bisect results makes much more send now
