Failed to initialize the second NVIDIA GPU in openSUSE 11.4

English Hardware
#1

I have 2 NVIDIA card intalled - GT 240 and Geforce 9500.
After updating by repo kernel to ver 2.6.37.6-0.5.1 and Nvidia driver by to ver 270.41.06 X server cant start

Part of X server log

So for now only dismounting one of cards gives working X server.

#2

did you make a separate entry in xorg.conf for each of the cards ?
for device0 and 1

#3

yes there is separate entries in xorg.conf for each card
i even tried to remove all entries about second card from xorg.conf
and even tried to delete xorg.conf to try autodetect
result was always the same

ps
if there is a need I can post my xorg.conf

#4

Now i reinstalled all the system (not recovered but REINSTALLED)
and problem is the SAME
and now i am assured for 99% that it is a bug in kernel (i tried pae, default desktop 2.6.37.6-0.5.1)
and nvidia .run ( 270.41.06 , 270.41.03, 260.19.44)

260.19.44 boots but second gpu sill dosn’t detects

I tested me hardware in other OS type and it works!!!

Do anybody have the same problem ???

Or any idea about fixing …

#5

Is there anything in post#62 here that might help:
openSUSE Graphic Card Practical Theory Guide for Users - draft version - post#62

#6

I belive that it is not a problem in xorg but driver & kernel

even if xorg.conf is blank problem is still present

#7

Now I got the solution but I DONT LIKE IT

If you are seeing severe stability problems and you are using a Linux 2.6 SMP kernel on a system with multiple processors (or processor cores) in combination with more than one GPU, please search the output of dmesg for the presence of the message below after the system has just been started:

PCI: Using MMCONFIG

If this message is present, please boot the system with the pci=nommconf kernel parameter and check if the stability problems continue to reproduce.

If your system is equipped with a dual-core processor, booting with the idle=poll and/or maxcpus=1 kernel parameters may improve reliability with some Linux kernels.

Similarly, forcing the clock source to HPET by booting with the clocksource=hpet kernel parameter has been reported to help on some systems. In order for this to work, you may need to enable HPET in your SBIOS and kernel configuration.

SO now I got half of my CPU
because in my case only using pci=nommconf maxcpus=1 kernel parameters helps

WE NEED NEW PATCHED KERNEL !!!**
