ECC memory and SMP lockups on Gateway 6400 server
Quoted 4 lines
Recently got the goahead to upgrade the Gateway Win2K server to a linux box to replace out old webserver. It's a 6400 server. 2 PIII-733's, 704 megs ECC registered ram.. NT ran fine on this box. not a hitch.
Could you check /proc/interrupts? Is one number extremely high?
And try to boot with "mem=690M". My sis boards become extremely slow if I don't limit the memory. I guess the e820 map is wrong, and one of the pages are actually power managmenet registes/NVS.

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

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.

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.
