Dual Core CPU on Abit NI8-Board

Hello!

I've a problem with my configuration and maybe someone of you can help me out.

My system looks like this:
Abit NI8 SLI mother board
CPU Pentium-D 2,8 GHz (dual-core)
1 GB DDR2-RAM (one module)
2x GeForc7800GTX grahpics adapter (to connect three monitors) kernel 2.6.17-rc1 (vanilla)

My problem ist, that a "cat /proc/cpuinfo" show's just one cpu-core if I boot with ACPI enabled.
If I disable ACPI by removing it from kernel or by passing 'append="acpi=off"' to my lilo.conf, the system is going unstable. It is freezing sporadical without any trace output. The freezes occur after a short time, especialy when I run OpenGL-applications - but also without OpenGL!

I have collected some information about my system here:
--------------------------------------------------------------
dmesg's output with acpi-debug enabled in kernel:

My kernels ".config"-file:
http://www.kpage.de/config.txt

The output of "cat /proc/interrupts" when ACPI is enabled:
http://www.kpage.de/interrupts_acpi3.txt

The output of "cat /proc/interrupts" when ACPI is disabled:
http://www.kpage.de/interrupts_noacpi3.txt

The output of "cat /proc/cpuinfo" if ACPI is enabled:
http://www.kpage.de/cpuinfo_acpi3.txt

The output of "cat /proc/cpuinfo" if ACPI is disabled:
http://www.kpage.de/cpuinfo_noacpi3.txt

And last, but not least: the output of "acpidump":

I've started a discussion about this problem on the linux-smp mailinglist. You can find some more information about what I've done by now here:

I have also contacted nvidia and abit - without response from abit by the time...

Who can give me a little help?

Thank you very much!!!

Hello again!

After contacting the Abit-Support I know, what is my problem...

My motherboard does not support FSB800-CPUs with less then 3,0GHz :-(
http://www.abit.com.tw/cpu_support/intel-pd-8xx.htm

So, now I have an expensive motherboard and an expensive 2,8 GHz cpu that won't work correctly together - funny, isn't it :-/
The next thing I'll do is to buy a 3,0GHz CPU and hope that this will work better...

Thank you very much for your support!!!

Greetings
Frank
