Bug#816283: nvidia-cuda-toolkit: cuda broken after upgrade (x86_64, Jessie, GTX980)

[Alois Schloegl]

Package: nvidia-cuda-toolkit
Version: 7.0.28-4
Severity: important

Dear Maintainer,



I tried to upgrade the nvidia-drivers from 352.41-1
to  the current version "352.79-3" and nvidia-cuda-toolkit to a matching
version, cuda became unusable. Rebooting the machine did not help.

I used the following two tests.

First, nvidia-smi reports this error:

  # nvidia-smi
  Failed to initialize NVML: GPU access blocked by the operating system

Second, I do have a short cuda program from here
https://github.com/leschzinerlab/Motion-correction.git
and can be installed with the following commands

    git clone https://github.com/leschzinerlab/Motion-correction.git
    cd Motion-correction/motioncorr_v2.1/src/
    make -B
    ../bin/gpuinfo

The compilation works without problems, but running the command
     ../bin/gpuinfo
results in this message:

    Simple GPU info query.

    You have 32720 nVidia GPGPU.

    DeviceID Name                    Version Memory(Mb)
    Failed to get GPU info of Device #0
    Failed to get GPU info of Device #1
    Failed to get GPU info of Device #2
    Failed to get GPU info of Device #3
    ...
    Failed to get GPU info of Device #32568
    Failed to get GPU info of Device #32569
    Failed to get GPU info of Device #32570
    Failed to get GPU info of Device #32571


I tried a number of additional things, like using the packages in
jessie-backports, and  nvidia-cuda 7.0 from debian/unstable. None of
these attempts solved the issue.


Best,
   Alois
