Usually it will be located under /boot with quite obvious name (suffixed with "debug" or similar) or you could just try to use vmlinux as the symbol file NB: make sure you use the very same debuginfo package with your current kernel version. Any slight difference could yield very different symbol addresses. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
