Hi all,

I'm testing an installation of nvidia drivers on a HP Z4 workstation
(nvidia Quadro P600) with CentOS 6.9. Running nvidia-detect with this
setup gives the following output:

  # nvidia-detect
  Error getting device_class

nvidia-detect also quits with exit-code 255.
Could this be a bug in nvidia-detect? Or is it an unsupported configuration?

The following hardware is detected, it seems some sort of unknown
Intel device is detected by the OS:

  # lspci | grep VGA
  00:1f.5 Non-VGA unclassified device: Intel Corporation Device a2a4
  21:00.0 VGA compatible controller: NVIDIA Corporation Device 1cb2 (rev a1)

  # lspci -n | egrep '00:1f.5|21:00.0'
  00:1f.5 0000: 8086:a2a4
  21:00.0 0300: 10de:1cb2 (rev a1)

Tested with the following version (with equal results):
