Sprio, thanks for the reply!
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 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?

As you said the space between kgdboc=ttyS0,? and 115200 also does matter. :)

Thanks
Shaji

Hello,

Same here. The only difference: It is not a vanilla 2.6.32, but a Debian
based 2.6.32-5-686 with only these things changed.

While booting the kernel Im using the following command line options 

kgdboc=ttyS0, 115200 kgdbwait

Do you have the space between "," and "115200"? I use:

? kgdboc=ttyS0,115200 kgdbwait

It works as expected.

I tried reordering the options with kgdbwait first, but both are not working.

I order for kgdbwait to work, it must be after kgdboc. That's what I
found out the hard way. ;)

I 
also tried kgdb8250 but no change. 

This one is wrong for 2.6.32.

Any help would be highly appreciated. 

Other than the space above, I do not see a big difference between your
setup and mine. Perhaps, the space is the problem? 

Best regards
Spiro.
