Problem with dual p3 serverworks motherboard

[Pedro Pla]

Hello,

I have been having problems with some new Intel SCB2 motherboards and 
1-2GB ram. The root partition is on a hardware raid 5 with the intel 
SCRMR raid controller. I first noticed the problem after getting a basic 
debian installed when trying to compile the kernel, initially it gave 
the typical signal 11 and segmentation faults which made me think it was 
a memory problem, however changing memory didn't help, after that I 
suspected it might be a mother board issue and moved to the other 
motherboard I had for tests, and it gave the same. After I thought it 
might be a kernel issue, so I tried every kernel since 2.4.17 - 
2.4.20-pre11 with the pre10-ac patches applied.. in many different 
combinations. Some kernels didn't even seem to boot without several oops 
in the mem_alloc.c:89. Others booted fine and seemed to be stable till I 
did anything that used ram (including the dd if=/dev/sda2 of=/dev/null) 
tests. Finally frustrated with my efforts I decided to see if it ran on 
a 2.2.22 kernel. No problems when booting but when trying to use any 
large amount of ram, or a kernel compile it gave the same errors. Could 
this be a hardware problem along all the hardware I bought? Or is there 
any known issues with this?
On a side note, I ran the memtest86 v3 and it gives no errors, however 
an earlier (2.8) version gives some errors in the ram?

Kind regards
Pedro

That really sounds like hardware

When the kernel (either 2.2.22 or 2.4.19) is compiled without smp there 
are no problems at all, I tried large memory movements and kernel 
compiles and all went smoothly. Could it still be a hardware issue?

Thanks,
Pedro

Yes

Alan saved me the trouble, it really sounds like hardware. Clearly you
don't use some of the hardware in a uni environment, even when it's
present.

I'd swap CPU's, try both MPS settings if you can, etc.
