I got the same outputs. So, if I understand correctly, I boot into the kernel without the kgbdwait option, and then manually launch the kgdb and then connect from Eclipse using gdb. The system waits at the root login prompt. Just so that I can see some quick results, can you suggest which file I could set a break point into, and monitor the registers and variable states at this stage, i.e. immediately after the root login?
