Problem

-

Every 3 seconds LINUX freezes for an instance - Appears as if computer has hickups.

Linux freezes for an instance every 3 seconds. This is accompanied by a concurrent flashing of the Hard Disk Access LED which means that something is accessing the disk every 5 seconds and is issuing an interrupt to the entire system. This does NOT happen before the kernel is loaded. At the boot loader menu screen the computer experiences NO such interrupts. Once kernel is loaded, then the problem starts and is present even before logging in to KDE session.

This happens with this version of Linux, which I must use for compatibiity reasons with my colleagues at work. I have also installed before a 32-bit version and it did not have this problem.

I have used top to try to identify any programs that are active with the same frequency as the phenomenon. Unfortunately no obvious catch. The program that appears to be more active relative to all the others is kacpid daemon. I have googled on it and I tried to disable it with adding the "noacpi" option in the default kernel line at /boot/grub/menu.lst file. This did not work as kacpid still poped up in the system after reboot. I am not even sure this is causing the problem though.

Anyone has ever come across something like that? Any ideas?

Thanx

Hard drive going bad perhaps? Do you have another one you could try?

It doesn't look to be Hard Disk problem because I can boot the machine with Parallel Knoppix from CD and this problem does not happen..

My first impression is that something might be going wrong with this version of kernel and multiprocessor AMD 64 systems. It might be also be some daemon of power management that does it but I have no idea how to disable such a thing apart from setting noacpi to kerne oprions which did not work anyway.

If you're running Knoppix from CD, then you're not really using the hard disk, or do you have a knoppix partition on the hd somewhere?
