Still no go.... I have downloaded the SRC rpm for kernel-2.6.9-11.EL.src.rpm <http://mirror.centos.org/centos/4.1/os/SRPMS/kernel-2.6.9-11.EL.src.rpm> I did rpm -i kernel....src.rpm cd /usr/src/redhat/SPECS rpmbuild -bp --target i686 kernel.xxx.src.rpm cd /usr/src/redhat/BUILD/kernel.XXX/linux.XXX make bzImage make modules_install make install When I reboot I get the same error about "mount: error 19 mounting ext3" Where should I go from here? Thanks, Jerry
