KGDB command line options not working for kernel 2.6.32

[Shaji Yusuf]

Hi all, 

Im using the following compile options for kernel 2.6.32
CONFIG_KGDB = y
CONFIG_KGDB_SERIAL_CONSOLE = y 

While booting the kernel Im using the following command line options 

kgdboc=ttyS0, 115200 kgdbwait

Neither is the kernel waiting for gdb connection nor is it sending any thing to 
the serial port. 


I tried reordering the options with kgdbwait first, but both are not working. I 
also tried kgdb8250 but no change. 


My serial console is working when I give console=ttyS0 option. So the serial 
interface seems to work fine.
I saw this problem reported by multiple people in different forums but there 
seem to be no resolution. I tried all the suggestions but none works. 


Any help would be highly appreciated. 

Thanks
