Default Re: Enabling SLI == hardlock at startx

instead of completely disabling ACPI try
acpi=noirq
pci=noacpi

I'm not sure it matters. The system still hard locks if I run glxgears. And please note, that's noapic. I'm not disabling acpi.

Have you tested with a 2.6.17.x kernel yet?

As I said before, getting a non-official kernel running on this box will take several days. I'm now out of town and won't be able to mess with this until I return next week. Since it's basically my "production" box, I'll see what I can do about creating a working .config and compiling the kernel.

Well, booting with noapic and acpi=off gets me in X,
replace acpi=off with pci=noacpi

SLI will not work without ACPI.
you may have ACPI conflict with whatever apci capable pci device, turning off acpi for pci will probably resolve your problem

obviously if the above did not work then testing new kernel is another option

my USB receiver is not being recognized properly much of the time.
set in GRUB
pci=noacpi (and/or acpi=noirq) noapic

whether this resolve SLI problem, I don't know,but probebly will take care of USB issue.
apic has not much to with usb so switching on and off apic will not affect usb, but will affect kernel booting

Locks up with 2.6.17 as well.

Are there any known problems with SLI, Abit AN8 and BFG 7800 GTX cards? I'm sort of at my wits end here.

I'm afraid that I don't have your motherboard here, so I'm not able to reproduce this. It seems likely that the problem you're hitting is specific to the motherboard.

Would remote access to the system help? I'd ship it to you, but I sort of need it...

Remote access wouldn't help for a number of reasons, the biggest being that you're getting a hard lock, so the system isn't going to be usable remotely anyway. If you could setup a serial console (locally) to capture any kernel messages at the time of the crash, that might be beneficial.

Barring that, we'd need a means of reproducing the problem locally in order to debug it further.

Thanks,

I can confirm this problem also. With the Ubuntu i386 kernel SLI works. But with the k7-smp kernel SLI hard locks X. Just a note with the k7-smp kernel with SLI off everything works good, accept SLI. This maybe and ubuntu kernel bug. But I was thinking it was because of Dual Core. And the Nvidia Drivers because i386 kernel has no smp support.

Ubuntu 6.06 LTS
linux-2.6.15.26-k7 smp enabled
Evga 6600 GT
Gigabyte GA-K8N-SLI
Amd Athlon X2 4400+

Last night, the system didn't hard lock. It's an oops in Xorg. I'll post the output from dmesg and the xorg log in a bit when I boot the system. And yes, I'm running the same processor and kernel.

Here's the files. Hope it helps.
