I root caused the issue by undoing my modifications and debugging again. The reason why kgdbwait did not kick in was that my point of debug was much before kgdb module loading.
I think I remember "kgdb early debugging" which says to compile the kgdb I/O driver not as a module, but directly in the kernel. http://www.kernel.org/doc/htmldocs/kgdb.html#CompileKGDB might give you a hint (I did not test it, though). I also see this: "If you build the kgdb I/O driver as a loadable kernel module kgdbwait will not do anything." (http://www.kernel.org/doc/htmldocs/kgdb.html#kgdbwait) This seems to proove my above point.
I think kgdb cannot be used for debugging my issue as i need to debug an issue much close to console init. Is there any way I can make kgdb load a little early?
see above: Does thie help?
As you said the space between kgdboc=ttyS0, and 115200 also does matter. :)
