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 Shaji Yusuf
