Hello I am trying to build a kernel with suse, i've used this technique on other distros and I don't know why it does work here. I am wondering if I have an in complete setup or I am simply missing a step. 1. Fresh Install 2. cd /usr/src/linux 3. make oldconfig 4. make 5. make init 6. make modules 7. make modules_install 8. make install 9. reboot The result is that the system will boot, but the kernel can not read the filesystem. FWIW, once this works, I will do a few more things with the system where I build a out of tree driver. I figure if my driver is failing, I should probably try to build the kernel as-is under non-modified setup. Any response appreciated. John F.

John F. Davis Hi Follow Larry Finger's tip in this thread about compiling the kernel. It works a treat :) http://forums.opensuse.org/pre-release-beta/421320-questions-help-regarding-...

Sounds like they are build as modules and you forgot to make an initrd. FWIW, this is what I do to build a vanilla kernel: 1. Copy /proc/config.gz to /usr/src/linux, ungzip it, rename it to .config and run "make oldconfig". 2. Run "make menuconfig" and edit the options. 3. Run "make bzImage" and copy /usr/src/linux/arch//boot/bzimage to /boot/vmlinuz-<version>. 4. Copy /usr/src/linux/System.map to /boot/System.map-<version>. 5. Run "make modules&&make modules_install". 6. run "mkinitrd -k <kernel> -i <initrd> -M ". 7. Edit /boot/grub/menu.1st. 8. Recompile my Nvidia modules since I have a Nvidia card.

These steps are done by simply issuing "make" and "make install". No need to get it done manually. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Simply doing 'make cloneconfig' does all that in one command :) But there is no need for doing that! If you haven't changed the kernel configuration yourself, you simply go to /usr/src/linux-obj/<architecture>/ and then go on compiling the kernel. That way you're able to compile multiple kernels from the same source whereas by doing 'make cloneconfig'

2. Run "make menuconfig" and edit the options.

3. Run "make bzImage" and copy /usr/src/linux/arch//boot/bzimage to /boot/vmlinuz-<version>. 4. Copy /usr/src/linux/System.map to /boot/System.map-<version>.

Simply doing 'make install' should DTRT. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That's sufficient.

You didn't compile it in, then. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

More likely forgot to build an initrd. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
