Is the kernel self-built? The debuginfo (vmlinux) should have the source file paths, so I think you need to install the source files there, if it's a different machine from one where the kernel was built.


# objdump -d -l vmlinux | less

it's cross compile. I have tried to mkdir the directory as "dis -l " output. and link to the dir the kernel was built. However, "dis -s xx" did not work
