Sorry for the noise :-| It's sane to do it the cp /boot/config-$(uname -r) .config && make oldconfig way, so the OP does understand what's going on and the /boot/config-$(uname -r) could be replaced to use any other wanted config, instead the one of the running kernel. I even didn't know that make-kpkg does it automatically. I would recommend to edit the config, to fit to the OP's machine before running oldconfig. # e.g. for Opteron/Athlon64/Hammer/K8 echo "CONFIG_MK8=y" >> /path/to/.config # e.g. 32-bit only # HIGHMEM from 4G to 64G echo "CONFIG_HIGHMEM4G is not set" >> /path/to/.config echo "CONFIG_HIGHMEM64G=y" >> /path/to/.config 2 Cents, Ralf _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
