[Moderator note: this post was originally incorrectly a report (not a response to) a post in Kernel & Hardware from 2015. That post dealt with Gentoo. This one does not. Separately, pengosunvidia posted a new thread shortly thereafter. As the two threads are about the same topic, I combined them. The separate thread was already in Unsupported Software. -Hu]

Post: post 7700494
Reason:

I am using ubuntu 16.04 server with one k80 card. Yesterday I was able to detect the gpu device and run tensorflow. Also nvidia-smi works well. But now the gpu device cannot be detected.

The error is shown as follows:

lspci
lspci: Cannot open /sys/bus/pci/devices/38b3:00:00.0/resource: No such file or directory

The I checked the files at /sys/bus/pci/devices/ and 38b3:00:00.0 was not found.

nvidia-smi
the command window freezes (i.e., does not return anything)

Can you help me working on this?

Thank you.
