Default How do I start diagnosing (not so?) random lockups?

It's possible my problem is not an NVidia problem, but these forums seem to be the most likely place for me to find some help.

I recently built a new machine, but seem to be experiencing ramdom lockups. Since it's not something I can cause to happen or find a consistent pattern for, I was hoping someone could give me a few pointers on where to start. If this information is already posted somewhere please give me a link.

Here is the (relevant) hardware I'm using:

ASUS M2N32SLI-Deluxe (NForce 590 chipset)
Athlon x2 4600+
Geforce 7600GT (x2)
USB Keyboard and Mouse

I don't have any problems when running a non-smp kernel. My lockups only seem to occur when the system is idle, but before the screensaver kicks in. I can still SSH into to machine after it locks up. I can use 'ALT + SysRq + B' to reboot the machine, but after the reboot I only have the 'lo' network interface - another normal reboot and my other network interface magically re-appear.

I'm using Debian etch (testing). It's a new install. I'm using kernel 2.6.17-2-k7. I've also tried the 2.6.17-2-686 kernel and it behaves the same. The only noteworthy things I have installed are Gnome, the NVidia 1.0.8774 video driver, and VMware Server.

I've looked through the forums and found several posts suggesting there are issues with smp and sli. I don't need to use sli, but I'm not sure if it was enabled by the NVidia driver installer or not.

Other posts suggest trying different kernel options. I have tried the following options without success:

noapic pci=routeirq pci=conf1
Since I'm still able to SSH into the machine after I experience problems I'd like to know what I can do to start diagnosing my problem. What logs can I looks at? What processes can I kill / restart?

Also, are there any known problems with my setup or similar setups?

I specifically bought this machine to play around with VMWare / Xen / Parallels, etc.. It's not a production box, so I'll try anything. It's not a big deal if it gets screwed up.

Thanks in advance,

I've been working on this for a little while and can add a bit of information. I think I can reproduce this problem by opening a virtual machine in VMware and leaving everything sit idle for about 2 minutes. It should make things easier to track down.

I think the following dmesg output may be relevant:

/dev/vmnet: open called by PID 4711 (vmware-vmx)
eth1: Promiscuous mode enabled.

[<f88674af>] (usb_hcd_irq+0x0/0x50 [usbcore])
Disabling IRQ #7
I'm starting to think my problem may be ASUS BIOS related. I'm currently using BIOS version 0406. I'll try to update to 0603 and see what happens.

Default Re: How do I start diagnosing random lockups?

I think I may have solved my problem.

I didn't update the BIOS on my ASUS board (having the bios flash utility lockup browsing my usb drive scared me away for a while).

I found a post in the ASUS forums that suggested setting the PnP OS Installed option to 'YES'. So far things seem to be working.

If I don't post again, consider this problem resolved.


P.S. This is the first ASUS board I've bought and it'll be the last.
