Hmmm, It looks indeed that it can happen only on already existing directories, I can't reproduce neither with a new build, and not everyone seems to be impacted by that bug neither, since some colleagues did the same thing without any trouble (with a completely different architecture though). So it's not that bad. However, when I do: In my source dir git checkout v3.9-rc1 In my build dir ARCH=arm make clean ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make zImage And then it breaks. So I suspect it's something not cleaned properly, or not generated properly. Here is what's left after the make clean http://code.bulix.org/eh1e6c-83108?raw Thanks, Maxime -- Maxime Ripard, Free Electrons Kernel, drivers, real-time and embedded Linux development, consulting, training and support. http://free-electrons.com
