I am trying to build 2.5.46 because I want to test with a kernel that includes the new sys_epoll support. I am following the instructions at http://www.digitalhermit.com/linux/kernel.html. I have managed to get through the make bzImage, make modules, and make modules_install. I disabled many config options (including a lot of EXPERIMENTAL options) to get everything to compile. I then copied the System.map file to /boot/System.map-2.5.46. I was unable to create the link from /boot/System.map to /boot/System.map-2.5.46 because there was already a link to /boot/System.map-2.4.18-3. I didn't want to delete that link because I want to continue to be able to boot my current version (2.4.18-3) also. I then copy bzImage to /boot/bzImage-2.5.46. My instructions then talk about what I need to do to configure lilo, but I'm not using lilo. Instead, as per the Redhat installation recommendations, I am using grub. So I modify /boot/grub/grub.conf. Here is the modified grub.conf: 1 # grub.conf generated by anaconda 2 # 3 # Note that you do not have to rerun grub after making changes to this file 4 # NOTICE: You have a /boot partition. This means that 5 # all kernel and initrd paths are relative to /boot/, eg. 6 # root (hd0,0) 7 # kernel /vmlinuz-version ro root=/dev/hde2 8 # initrd /initrd-version.img 9 #boot=/dev/hde 10 default=0 11 timeout=10 12 splashimage=(hd0,0)/grub/splash.xpm.gz 13 title Red Hat Linux (2.4.18-3) 14 root (hd0,0) 15 kernel /vmlinuz-2.4.18-3 ro root=/dev/hde2 16 initrd /initrd-2.4.18-3.img 17 title Red Hat Linux (2.5.46) 18 root (hd0,0) 19 kernel /bzImage-2.5.46 ro root=/dev/hde2 20 initrd /initrd-2.4.18-3.img I added lines 17-20. Note that I use bzImage instead of vmlinuz. I'm not sure about that. I also don't know if I should modify the initrd line. Anyway, when I boot, I get this error: Kernel panic: No init found. Try passing init= option to kernel. Does anyone have any ideas? Should I try starting over with 2.5.47-ac2? Thanks. Mark. -- Kernelnewbies: Help each other learn about the Linux kernel.
