not able to boot with new and existing kernel in ubuntu
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 22.214.171.124 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?
