not able to boot with new and existing kernel in ubuntu

embeddedlinux · 05-10-2012, 11:32 AM

Hi all,
I downloaded latest kernel 3.3.4 source from kernel.org, compiled it successfully(make), did make install and added to grub.conf file. Now when I tried to boot from 3.3.4 I am getting kernel panic and if I try to boot from existing kernel 2.6.38.8 then, I am not able to get the kernel selection window at the start of boot every time. I tried to restore back by removing the 3.3.4 kernel with some commands mentioned in the forum but with no success. Any help?

Thanks

I never do a 'make install' with a kernel because it thinks it knows where everything is and what bootloader you're using, and it's wrong.

If you can boot on an install cd, mount your drives (You need /, usr, & /boot if they are separate), cd to the kernel top source (I'm presuming /usr/src/linux-nnn) and try something like

cp arch/x86/boot/bzImage ../../../boot/your_kernel_name
cp System.map ../../../boot/System_map_name
make modules_install
