Old computers uses 100% processor time?

[MKas]

Hi,
I have a problem. I'm trying to run program, but it use 100% processor time.
My computer is single core.
If I run on dual core processor, then everything works fine.
One more thing.. On windows that program works fine on both computers (single-core & dual-core).

Maybe someone knows how to fix and what to fix?
Thanks

No programme should use 100% of your CPU time... If it does that then it contains a bug. This used to be a common problem with some earlier versions of Mandriva (for example).

The first step is to open a console and type 'top'. That will give you a list of programmes and an idea of what is using your CPU. If that programme isn't essential I would kill it and remove it. You might find that later versions don't give you that problem.

The bug is in Linux Kernel. With newer than 2.6.20 version was bad. So I tried to install fc4 with 2.6.11, then I update to 2.6.17 and everything works fine. I'm working with that program so it is very essential.
