Hi again wwp!

It yields a lot of information about what is there.  Sometimes you
find that things are competing for the same memory address space or
non-shareable IRQs .. etc.  You also have information about what you
have that is very helpful in Google searches.

I was thinking you may be using an older machine.  You have a very nice machine.

That understood I fall back to wondering if there are known problems
with your chip set, especially in respect to your hard drive and video
card. I note with interest that your video driver falls back to pci
mode rather than pcie (see: man radeon)  You may do well to look into
a new video driver (Google "Linux Ati X600 driver").  You may look
into whether a CMOS update is available.

Other than that, the problem seems to be related to the unit being on
for a long time?  If so, look for possible overheating (CPU
temperature, airflow restricted by wiring, long carpet, bad fan motor
or fan control SW...).  If still nothing, look into possible AC power
problems or computer battery problems.  You will probably solve the
problem long before you get to this paragraph.

Good Hunting!
