=== Cleaning up...
We either have to compile mkvmlinuz with -fno-stack-protector or define
that function somewhere. I assume a patch for the kernel is required for
that.
I tried to recompile mkvmlinuz with the flag -fno-stack-protector. Added
to mkvmlinuz-23ubuntu1/boot/Makefile in the mkvmlinuz package and then
tried to create the kernel with the new object files and it worked just
fine. The kernel even booted without problem afterwards.
I don't know which solution is the way to go, patch the kernel or add
the flag -fno-stack-protector to mkvmlinuz.
