Hi everyone

I have a weird issue with my T620:

For a couple of months now, it's been running with 2 Tesla K80 just fine (mostly machine learning stuff)

A couple of days ago, I got a Quadro RTX6000 and replaced one of the teslas and here's what's happening:

1st boot, new pcie found, reconfiguring and rebooting

on 2nd launch, it's telling me that: A bus fatal error was detected on a component at slot 7.

switched the card to another slot, same error after 2nd restart, just a different slot.

I also went in a little deeper and replaced the quadro with a 2070 super just to see if it's working, same fatal error even for the 2070.

Weird thing about the Teslas is that, it uses that weird cpu connector which splits into 2 pcie power connectors, that works fine. However, the other cards have a 8pin pcie and a 6 pin pcie, use less power than the teslas, and it doesn't like it for some reason.

it's running a xcp hypervisor, the teslas do show up with lspci | grep 3D, quadro or 2070 not at all
