Hi, I am sure somebody has reported this but I dont have the answer yet :-); I installed the kernel source rpm -ivh kernel-source-2.4.3-20mdk.i586.rpm then cd /usr/src/linux make mrproper make menuconfig select config I want save the config at /boot/config-2.4.3-20mdk after make a backup current file make dep make bzImage make modules back up the /lib/modules/2.4.3-20mdk make modules_install (no error message here when it run depmod ) copy kernel image to /boot/2.4.3-20mdk copy /usr/src/linux/System.map to /boot/System.map-2.4.3-20mdk (after backup the orig file) edit /etc/lilo.conf, choose the new kernel image; I dont use initrd. Run lilo Restart Now it spits a lot of unresolved symbols and can not insmod any modules at all. I really dont understand and get totally confused. I never have such strange things when I used Debian or Slackware. Thanks in advance.. ===== S.KIEU _____________________________________________________________________________ http://messenger.yahoo.com.au - Yahoo!
