Where does this load come from?

[Jurgen Kramer]

Hi,

I am seeing some strange load figures on my P4 Celeron based system
which I cannot explain. There always seem to be some load while there
are no real apps running. Stopping all daemons doesn't seem to effect
things at all.

Output from top with 2.6.4-rc1:

 13:16:38  up 38 min,  1 user,  load average: 1.67, 1.74, 1.57
62 processes: 59 sleeping, 3 running, 0 zombie, 0 stopped
CPU states:  47.5% user  52.4% system   0.0% nice   0.0% iowait   0.0%
idle
Mem:   515552k av,   93544k used,  422008k free,       0k shrd,   10980k
buff
        49632k active,              29284k inactive
Swap:  265064k av,       0k used,  265064k free                   59836k
cached

Is this a real problem or is top screwing things up here? 0.0% idle
doesn't seem right as for the load average. This system runs on RH9.

Compared to my P4 HT system running 2.6.4-rc1 on Fedore Core-1:

 13:17:42  up 30 min,  5 users,  load average: 0.12, 0.63, 0.64
91 processes: 90 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:  cpu    user    nice  system    irq  softirq  iowait    idle
           total    1.2%    0.0%    0.4%   0.0%     0.0%    0.0%  198.0%
           cpu00    0.9%    0.0%    0.1%   0.0%     0.0%    0.0%   98.8%

This looks more like it.

What can be the problem here (if there is a real problem)?
