Argh.  Even using the 185 driver from the nvidia website didn't help (did the --purge deinstall etc of course).  Still getting computation errors after 1 or 2 seconds.  Next I'll keep the official nvidal 185 driver and try using the 8.10 kernel but I'm not too hopeful at this point...   :(

Tye please post your xorg.conf and xorg.0.log here. Also do a ldd on your cuda app and post here.

There is something I don't understand. Your xorg.0.log says:
(--) PCI: (0@1:0:0) nVidia Corporation GeForce 9600 GSO rev 162, Mem @ 0xcc000000/16777216,

So to X server your cards appear the same. On the cuda error you posted above the cards are completely different (totalGlobalMem, clockRate, multiProcessorCount) :
   Device 1 : GeForce 9600 GSO
           totalGlobalMem = 804585472
           sharedMemPerBlock = 16384
           regsPerBlock = 8192
           warpSize = 32
           memPitch = 262144
           maxThreadsPerBlock = 512
           clockRate = 1350000
           totalConstMem = 65536
           major = 1
           minor = 1
           textureAlignment = 256
           deviceOverlap = 1
           multiProcessorCount = 12
   Device 2 : GeForce 9600 GSO 512
           totalGlobalMem = 536608768
           sharedMemPerBlock = 16384
           regsPerBlock = 8192
           warpSize = 32
           memPitch = 262144
           maxThreadsPerBlock = 512
           clockRate = 1600000
           totalConstMem = 65536
           major = 1
           minor = 1
           textureAlignment = 256
           deviceOverlap = 1
           multiProcessorCount = 6

Which one is the truth? I think your xorg.conf will need some adjustments. I'll research further.

Also please do one more thing, go to synaptic and install strace. Then run boinc with:

strace -ffv boinc

Let it run for a few seconds to let cuda destroy some workunits. strace will produce some debugXXXXX files from the failed cuda runs. Tar them up and attach them here.

Thanks.

I moved some cards around to make them match the first card now.  I've been trying lots of things to see what might help.  Unfortunately making both the same wasn't helpful...  ;-)   Good catch, sunu!

I will try the strace once I can get more workunits to be sent...

There was some strace text output (it didn't make any debugXXXfiles), but I didn't see anything useful in what I could capture in my buffer.

BTW, the 9.04 kernel did have an update recently, to 2.6.28-13 rather than the 2.6.28-11 that it shipped with.  Does the newer kernel still have the same problems?

Both 2.6.28-11 and 2.6.28-12 have problems. I think I saw somewhere that also 2.6.28-13 has problems.  I say ditch ubuntu's 2.6.28 kernel altogether and use something else. Myself am running ubuntu 9.04 with 2.6.27 kernel from 8.10.

Sorry for the strace error. Use:

strace -ffv -o debug boinc

Now you'll see those debug files.

Also go to /dev and tell me how many nvidiaX devices you see.

Lets try some xorg.conf tweaks. Below the current "Device" section add another one for your second card, something like this:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BusID          "PCI:01:00:0"
EndSection

Section "Device"
    Identifier     "Device1"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BusID          "PCI:03:00:0"
EndSection


On the "Screen" section add:

Option "SLI" "False"

Actually, to take variables out of the system until I nail down this CUDA thing, I've taken out the 2nd GPU, so I'm only running on one.

I'll try the strace thing again, but right now the projects out of workunits again...

Also, I'm willing to use the 8.10 kernel but I can't seem to make it install with my vbox stuff.  Any hints?

What problems do you have? I don't have any problems with 8.10's kernel and virtualbox 2.x or 3.0.

When it gets near the end of the kernel packages install, it fails on adding two things for virtualbox into the kernel.

Does the install fail altogether? If not I don't think it's a problem. In my /lib/modules/2.6.27-14-generic there aren't any virtualbox modules, while there are in my /lib/modules/2.6.28-13-generic and /lib/modules/2.6.28-13-server and still virtualbox runs ok. It just doesn't like module kvm_intel, so before starting a virtual machine I do a sudo rmmod kvm_intel or sudo modprobe -r kvm_intel .

Hmmm, don't think it failed altogether (the kernel stuff was listed as installed and showed up in the menu.lst), but I was loathe to try to boot into it with the failed insertions - not sure what else might have burped.  Still, I'll try it tonight.  For now, I've gone back to the 180.44 driver and have been Seit-CUDAing fine again (but with the CPU hit of course).

If I just try with the -image and the -headers packages, the -headers fail, but the image installs and shows up in the menu.lst.  Is that all I really need?  I get the error that the -headers package can't be installed because it depends on itself.  ;)

BTW, the modules that fail now are nvidia (180.44), vboxdrv (2.1.4), and vboxnetflt (2.1.4).
