how to debug my kernel

[冯硕]

The most simple solution may be to use serial console :-).
You need a dummy (with cross TX/RX) serial cable connecting the box with
your modified kernel as the 'debug end' and another Windows/Linux box as
'console'.
Boot your kernel with parameter "console=ttyS0,115200" (or any speed your
console support), and set your console properly ("remote terminal" on
Windows or minicom on Linux), then you can see the kernel output on your
console.
Set the screen buffer of your console as big as you wish. :-)
