I never had the high Kernel & System CPU usage, but I saw this issue on a friend's computer.

The process with PID 4 had a high CPU usage. But that issue solved itself.

However, how is disabling HDD timeout (spin down after ** minutes) meant to solve the CPU usage issue? How is it related?

You'd have to evaluate the threads on the system process, determine which is utilizing the CPU and from there determine what the thread is doing.
