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 -- Name: Frank von Daak eMail: f.vondaak@kpage.de Homepage: http://www.kpage.de "It takes a revolution, to make a solution! Bob Marley"
