Hello

I've searched the internet but I couldn't find the answer.
KDE's system guard shows that something is using almost 100% of CPU, but it doesn't want to tell me who.
If I run top I get this:

top - 16:13:13 up 4:13, 1 user, load average: 1.27, 1.57, 1.63
Tasks: 109 total, 1 running, 108 sleeping, 0 stopped, 0 zombie
Cpu(s): 4.0% us, 0.7% sy, 0.0% ni, 0.0% id, 95.3% wa, 0.0% hi,

Your machine is 95.3% WAIT state, which means that the machine
is waiting on slow peripherals, like perhaps a disc. This can
be a result of waiting on virtual (swap).

0.0% si
Mem: 516416k total, 504260k used, 12156k free, 38204k buffers
Swap: 522072k total, 752k used, 521320k free, 148256k cached

But it looks like this isn't the problem, since you have used
only a teeny amount of swap.

Are you perhaps printing a large job? I have also seen prelink
do this sort of thing to a machine, as it goes plowing through
your disc looking for nothing to do. Use all your senses. Listen
to your discs when this happens.
