Hi Stefan,
is there a reason, why you don´t use the sources from Debian ?
If you use Debian you should use theire sources, because they are already
optimized for the Debian system. If you try to compile and use a kernel of
vanilla.org, you might get some difficulties, as the vanilla-kernel might be
a little bit different from the Debian kernels.
My suggestion: Use the kernel-sources of your distribution.
The other way might be to edit the .config itself.
If this fails, too, I myself fail, too. :)
regards
Hans
