Dual Core CPU on Abit NI8-Board

Dual Core CPU on Abit NI8-Board

[Frank von Daak]

Hello to all!

I hope that this is the right place for me to report my problem - if not, 
please tell me!

Some days ago I've purchased a new motherboard, cpu and graphics-adapters.
The board is called "Abit NI8 SLI" which has a nForce4-Chipset and a socket 
775.

http://www.abit-usa.com/products/mb/products.php?categories=1&model=280

The CPU is a Pentium-D 2,8 GHz. And the graphics-adapters are two 
GeForce7800GTX-Cards...

My problem is, that a "cat /proc/cpuinfo" shows me just one cpu with one core. 
I've tested this with kernels 2.6.16.1 and 2.6.17-rc1 (x86 and x86_64)

If I add the following line in my lilo.conf to the kernel, I can see both 
cpu's:
append="pci=noacpi pci=routeirq noapic acpi=off"

After this my cpuinfo looks like this:
http://www.kpage.de/cpuinfo.txt

and dmesg say's this:
http://www.kpage.de/dmesg.txt

But if I do so, the machine is running very unstable and is hanging after a 
while. The crashes will happen espacialy if I run OpenGL-Applications like 
"glxgears".

Can someone of you tell me, what I can do to fix this problem?
If you need further information, please tell me!

Thank you very much and greetings!
Frank

Hi Frank:

This sounds suspiciously to me like those kernels don't have SMP support
built in.  Are those kernels you built yourself or obtained from your distro?

I've build them myself with smp-support enabled. I've also tried a 
debian-smp-kernel with the same behaviour...

This is what "cat /proc/interrupts" and "dmesg" says when I boot the kernel 
with no options: (append="")
http://www.kpage.de/interruptsacpi.txt
http://www.kpage.de/dmesgacpi.txt

Sorry, I can't tell you what it say's, because my machine does not boot with 
this option's. At the moment the machine is hanging after rebooting with this 
options and I've no more remote access to it. Because I'm at work now, I can 
go on in 7 hours...
I've tried some of this options yesterday with almost the same result (system 
is hanging) - I don't get error messages like a segfault on screen - the 
machine is just hanging...

Frank

Re: Dual Core CPU on Abit NI8-Board

[Frank von Daak]

ok .. after I've found a way to reboot the machine remote [by my mother :-)] 
I've tried the following append-line:
append="pci=noacpi pci=routeirq noapic acpi=on"

acpi is now on - but just one cpu :-(

And this is what dmesg and /proc/interrupts say:
http://www.kpage.de/dmesgacpi2.txt
http://www.kpage.de/interrputsacpi2.txt


This is the output when I append the following line (append="pci=noacpi 
pci=routeirq noapic acpi=off")
http://www.kpage.de/dmesgnoacpi.txt
http://www.kpage.de/interruptsnoacpi.txt

The only problem in this case is that the machine is very unstable on 
3D-Action...

any more ideas?

Thank you very much!!!

yes and no :-}
I've attached the two cards in SLI-Mode to the board. This means that I've 
placed the chip for SLI-Mode (you can see the red chip on this image between 
the two pcie-slots: 
http://www.etech4sale.com/images/0146000_0146999/146929_h.jpg)

This must be done, to run both pcie-slots in 16x mode. If not, only one slot 
is 16x the other is 1x.
And I've connected both cards with a SLI-bridge - but: 
I don't run use the SLI mode in linux!

I'm running a flightsim (x-plane) and have connected three monitors. Because a 
normal graphics-adapter can handle just 2 monitors there was the need for two 
graphics-adapters.
And they are running fine, if I don't append anything in my lilo.conf! But I 
can use just on one cpu-core :-(
I'm not sure if this is realy a problem with the x-server, or?

But I'm really unsure: whats my problem? SMP or Nvidia?


>You're welcome since my last message just hang your machine :))
hehe - that's really no problem!!!

   Probably the best step to take next is to take another pass through a kernel.
It seems like you have a lot of things built in which aren't necessary to boot
(your network card, for example).  I generally recommend putting as much as
possible into modules so that you can boot with the bare minimum of stuff.  If
it works that way, you can start slowly adding things and figure out with better
granularity what's causing it to freeze.
   You'll use a little more memory that way (modules load in on page boundaries,
so one could in theory be wasting n * ($PAGE_SIZE - 1) bytes in loading n
modules, but the flexibility is very well worth it when figuring out problems
like this.
   I have a few prejudices to begin with for your short list of what's causing
the box to die.  The first is DRI.  The second is one of the NFORCE drivers.
The fact that glxgears seems to trigger the problem and that I dislike DRI in
general sounds like a good place to start ; )

Re: Dual Core CPU on Abit NI8-Board

[Frank von Daak]

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?

Hi!

After another day of debugging my "smp-problem" I've enabled ACPI-debugging in 
kernel.
Maybe someone of you can take a look at dmesg's output and interpret the 
messages:
http://www.kpage.de/dmesg_acpi3.txt

I think the following messages tell something about my problem:
acpi_processor-0495 [06] processor_get_info : Error getting cpuindex for 
acpiid 0x1

I suggest that you ping the acpi development list about this:
  linux-acpi@vger.kernel.org

You'll probably need to provide the ACPI firmware tables from your computer.
Use pmtools (acpidump) to do that.  If you don't have them installed already,
you can get them here:
  http://www.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/
Grab the latest pmtools tarball.

Re: Dual Core CPU on Abit NI8-Board

[Frank von Daak]

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!!!
