Thank you for your advice. I understand (and enjoy) the implications of 
working with such a new patch.

Regarding disabling of the stated configuration options (tracing and 
KGDB), I am having a problem that may be quickly answered.

As you can see in the attached images, sparse irq numbering and kernel 
debugging are locked 'enabled'. How did this happen? How can I disable 
these options safely?

Thanks!
