Suspend to Disk failed, now machine's CPU usage makes machine unusable

On my laptop, I have SUSE 9.3 installed. The laptop is a 850 MHz AMD Duron (Compaq). Linux runs great.

I decided to try the "suspend to disk" feature. The dialog in KDE was showing progress, as the "ram" was being written to disk. It got over half way and hung. I let it sit for a while, thinking it would finally finish, but it didn't. Finally, I ended up having to power the machine off manually (locked up).

Now, the machine boots up fine, but is extremely slow. I have found the CPU usage averages anywhere between 40% and 60% all the time, which obviously isn't normal. As a result, my laptop quickly overheats, and the machine becomes unstable - virtually unusable. Subsequent reboots don't fix the problem.

Making suspend to disk work isn't the issue here... how do I undo the damage done by the suspend to disk feature so my machine works again?

run top to see what is using all the CPU bandwith.

Code:

man top

Then kill the process by its PID, example

Code:

kill 128

See why the process is running.

The processes aren't unusual. Its the amount of CPU time that they are taking.

I have verified this is a KDE problem. I can run Gnome just fine. KDED hangs around 40% utilization. Kopete now fails to connect (it doesn't even give an error - just sits there).
