The OEM 128 and 64 meg sitck of ECC that came with the machine works
fine. I got an aftermarket ECC stick that NT likes but linux doesn't.


Standard boot with no extra kerenl switches
and it's very slow and CPU load is 1.0

           CPU0       CPU1

Booted with "kernel-2.4.18 mem=704M" at lilo prompt and it's still slow

Kernel command line: auto BOOT_IMAGE=Linux-2.4.18 ro root=802
BOOT_FILE=/boot/kernel-2.4.18 mem=704M

is what dmesg cought.

Moby:/proc # cat interrupts

I finally got the machine stable with SMP enabled in the kernel (had to
be a heat issue and the mobo shutting things down)

I'm about to compile and use  http://www.anime.net/~goemon/linux-ecc/ 
to see if I can figure out what exactly is happening.
