I am trying to add a GPU to an Ubuntu 20.04 system and found that when I add the GPU the network interface stops working. I think I have narrowed it down to the fact that the PCIe address of the network adapter is bumped by the GPU VGA and sound interfaces. ‘lspci’ shows me the address changes from 8.00.0 to a.00.0
What can I do? Options I can think of, but don’t know how to implement:
- Rescan the hardware (like Windows can)
- Remove the ethernet driver/device and add it again
Both of these need to be done from ssh command line, I have not got gnome desktop.
Clues and pointers very welcome!
