只好尋找其他方法：使用 make-kpkg。
$ sudo apt-get install kernel-package
$ sudo make-kpkg clean
// 編譯，結束後會在父目錄生成兩個文件：linux-image-xxx.deb和linux-head-xxx.deb
$ sudo make-kpkg --initrd --append-to-version=linux-2.6.10-1 kernel-image kernel-headers

都不行，只好祭出大招了：安裝 ubuntu-6.06.1-desktop-i386.iso ，它的內核版本是2.6.15.
一切都重歸平靜...
