I have an intermittant problem with a laptop running Ubuntu 6.06. It'shave you done a memory upgrade from the original configuration? If
got a Core duo processor, 2 gigs of ram, a sata drive, an Intel board

that can scope out bad hardware. I know of memtest86, and the results
Every time I've run a program that is memory intensive, the machine
crashes. It just stops, as if someone pulled the plug. Nothing is
written in the logs to indicate what the problem is. This has happened
about six times. In between these failures, the machine runs fine --
i.e. when I use it as a lightweight desktop for Firefox, T-bird,
rhythmbox, gnome-terminals, and occassionally OpenOffice and Gimp.
It's generally up 24 hours a day (without the battery in), and shows
no sign of trouble until I do something more demanding.
One day, I did an extensive test with memtest86. The ram is in two
modules so I was able to test one, then the other and both. With both
modules in, the machine crashes early in the first iteration -- just
like the other crashes: pffft and the machine is dead. There is no
report of problems before this happens. I have to restart to get the
DVD out. With either module in, memtest will do one or two iterations
successfully, but it crashes with each one after a few loops of the
default test set. I suppose memtest is exposing some other hardware.
so, is it possible that the wrong memory for the that particular system
was installed? i.e. wrong clock speed etc.
No. The two gigs was vendor-insalled at purchase time. btw, this is a
System76 machine, and the two memory modules had the same labeling --
Corsair Value Select.
