Hi jd:
When system(linux-2.4.0-test6-rmk5-np2) boot up & I run command "top", it
shows up the following status & LED D9 always light on : (why?)
Mem: 26688K av, 23708K used, 2980K free, 0K shrd, 18432K buff

The CPU % of kswapd is almost 100% ! That means kswapd is a compute-intensive
program?

I will assume that you're talking about the Intel Assabet board.
D9 (the red one) illuminates when the system is not idle. A compute-intensive program
will generally cause this LED to be
activated. Since you say it's always on, you might check for a runaway process or
thread.
The code to control the Assabet LEDs is in linux/arch/arm/mach-sa1100/leds.c.
