What is the best tool for debugging kernel Redhat's os 3? i presume it doesn't matter which version of kernel you are running? Does your kernel have to be compiled with debug support enabled to use gdb?
If I want to run gdb /usr/src/linux/vmlinux /proc/kcore would vmlinux have to be compiled with special flags?
