Re: Dual Core CPU on Abit NI8-Board

[Frank von Daak <f.vondaak@kpage.de>]

Hi!

I'ld like to sum up, what I've tried to solve my smp(?)-problem:

- I've bootet my vanilla 2.6.17-rc1 kernel with the following options appended 
in "lilo.conf":
1. noapic
2. pci=noacpi
3. pci=biosirq
4. pci=routeirq
5. pci=conf1
6. acpi=off

and I've tried to combine most of the options together. (very much reboots as 
you can believe :-})

- I've started my x-server with just one geforce card.
- I've disconnected the SLI-bridge from my card and put the board into normal 
(not sli)-mode. (In this case the board has one 16xPCIe and one 1XPCIe-Slot. 
In the other case it hase two 16XPCIe-slots, and the gra.-cards are sharing 
one irq)
- I've removed PREEMPT from the kernel
- I've tried kernel 2.6.16.1 and installed a 64Bit Debian with 2.6.15
- I've removed the usb-module so that the graphics-adapters don't have to 
share an irq with usb
- I've upgraded my motherboard-bios to the latest version
- I've tried some different bios-settings (low cpuid for example)
- I've contacted nvidia - they also have not heard about this problem

The result was always the same:
If I start the kernel with ACPI the system is running rock solid, but I have 
just one cpu-core.
If I start with disabled ACPI the system is hard-crashing after a short while. 
(Sometimes it is crashing without starting an OpenGL-app!)


So I have no more ideas at the moment...
Should I go and buy a new motherboard?

Greetings
Frank
