Hi all!

I've configure all `CONFIG_DEBUG_` related options to `y`,but when I
try to debug the kernel,it says no debug symbols found:

    gdb /usr/src/linux-2.6.32.9/vmlinux /proc/kcore

    Reading symbols from /usr/src/linux-2.6.32.9/vmlinux...(no
debugging symbols found)...done.

And I've checked with `make V=1` that there is the -g flag.

Why, is this a known issue?

Thanks in advance!
