(The warning in the documentation is about -5 errors, though). I disabled it and the errors also disappeared. But the time of writing of this warning is 2.6.26 ; is it still relevant ? If so, I would be interested to try and fix it (I'm doing an internship which subject is MTDs) -- David Wagner, Free Electrons Kernel, drivers, real-time and embedded Linux development, consulting, training and support. http://free-electrons.com
