The debugging stuff is all stripped out when the kernel is installed into /, however it remains in the kernel.debug file in your kernel build directory: if you haven't rebuilt your kernel since, you can use this kernel with gdb and the vmcore image (it must be the same one as the kernel which panicked and dumped the vmcore, otherwise it won't work properly).
