I'm experiencing similar problems on a DELL Optiplex 740 with the same 
CPU (AMD Athlon 64 X2 Dual Core Processor 5000+ @ 2.60 GHz, 4 GB RAM, 80 
GB Hitachi Deskstar 7K80 HD).  But in my case the slowness is not 
restricted to OO, but the whole systems is slowed down.  Even simple 
actions (e.g. starting a Gnome Console) bring the load up to over 2. 
Right after booting, the load is usually over 2, sometimes even up to 4. 
  The slowness can literally be seen during the boot process.  The 
problem occurs since kernel 2.6.18-194.el5.  I measured the boot times 
(from GRUB to gdmgreeter, booted with 'noapic'):

kernel 2.6.18-164.el5      1"03', load after boot: 0.5

kernel 2.6.18-194.el5      3"35', load after boot: 2.5
kernel 2.6.18-194.3.1.el5  3"30', load after boot: 2.3
kernel 2.6.18-194.8.1.el5  3"35', load after boot: 1.9

When shutting down from kernel 2.6.18-194.x, I often (around 7 of 10 
times) get the following error on the console:

The complete console of the boot process can be seen on 
http://pastebin.de/8808, the console output of the shutdown/reboot 
process is on http://pastebin.de/8809.  Bootcharts of the two boot 
processes can be seen on http://www.drosera.ch/kernelproblem/.

Memtest has been run w/o result.

Is there a way to narrow down the problem before posting a bug report?
