Hi all,

I tried to use Fiasco.OC without the kernel debugger, respectively with
the following config changes:

> diff --git a/repos/base-foc/config/x86_64.kernel b/repos/base-foc/config/x86_64.kernel
> index 07159da20d..8b8b1c8c50 100644

It compiles without any errors but the execution fails with multiple
messages of:

> KERNEL: Warning: nothing mapped: (Obj_space) from [0xffffffff81fd1e90/ffffffffffffffff]: 000000000000000a size: 0000000000000001 to [0xffffffff81fd1d80/ffffffffffffffff]

Are there any further requirements to use foc without the kernel debugger?

Regards,
Johannes
