Option "debug" is for UML, not for coLinux.
You can run an UML-Linux-Kernel and you can debug it.

But, you can not debug the coLinux kernel or modules. coLinux kernel
runs directly on the native CPU, there exist no dispatcher or hypervisor
for debug. In source exist some ideas for debugging, but they are not
finished and have no interface to GDB.

Debugging modules directly via /dev/kcore is not supported by coLinux.
It was disabled, because the physical memory of native Linux is pseudo
physical memory (and not linear) under coLinux.
