Well, the cmdline I added is the switch of early
console enable, which I should enable 
CONFIG_SERIAL_8250_CONSOLE in kernel config first. A
new and nice feature of 2.6.x to me.

I don't have such experience. If possible, could u
give me a linkage or doc for me to have a look?

For the moment, I don't have such a cute hardware 
tool which can support source code debug like 
BDI2000. To be frank, I haven't used a hardware tool 
to debug kernel. Perhaps the problem I met wasn't 
complicated to use it. But now it is another story:-)
BTW, Could I use KGDB to try it?
