The solution is to edit /etc/mkinitrd/modules and add ext2 and ext3. Then all is well and one gets a initrd kernel built properly. It should be noted that my config file was the same one as the stock binary kernel package 2.4.17-686 that is available in debian/woody. Perhaps some kind of warning should be issued by the make-kpkg package to the effect that might have to edit some files. -walter
