This weekend i tried to compile a patched 2.6.35 kernel and wanted to install this on multiple machines. But it kept failing when the .deb files were created.
make-kpkg kept complaining that the kernel version, 2.6.35-rbd+ was not in the “control info”.
After some searching i found out this was due to CONFIG_LOCALVERSION_AUTO not being set.
Setting this to ‘y’ solved it for me, now my kernel compiled and got packed the way it should.
