Well usually the processes that would rather be doing something else are 
blocked on IO if they are blocked at all.  On top this would show up on 
top as a lot on CPU on "system" and no idle CPU.  Maybe there is some 
problem with the install kernel vs your board?  Try

dmesg

and see if there is some spew of something going on, maybe with your 
HDD.  Also I guess check your

cat /proc/cpuinfo

and also see if anything on

cat /proc/interrupts

is cranking up at a crazy rate.  Another trick is to do

ps -Af

and look at the last few processes, usually that list is in order of 
spawning, so you can see if a scriptlet is running something that is 
making it stick.
