I have a “gaming” pc with MSi RTX 3080 purchased 3 months ago - I have Ubuntu 20 with lambda stack installed (Lambda Stack: an AI software stack that's always up-to-date). Everything was working fine, until yesterday when a process with pytorch running on GPU froze. After reboot, nvidia-smi returns:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Here are some other commands I run to help with the diagnosis:

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Device 9bc5 (rev 05)

$ nvidia-detector
None

$ sudo lshw -C video
  *-display

I did try to reinstall the drivers a couple of times, but it still seems that the OS is not seeing the GPU.

I’m also attaching the nvidia-bug-report.sh output

here’s my log file.

I already contacted the hardware vendor, please let me know if you have any ideas about this issue.

The nvidia gpu is gone. Please try disconnecting power, reseat the card in its slot. If it doesn’t reappear, it’s dead, have it replaced.
