            Bug ID: 108521
           Summary: RX 580 as eGPU amdgpu: gpu post error!
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu

          Reporter: rstrube@gmail.com

Hello everyone,

I've been attempting to get my RX 580 working correctly as an eGPU using the
Akitio Node eGPU enclosure (over Thunderbolt 3).

I've confirmed that both the Akitio Node and my laptops Thunderbolt 3
controller are running the most up-to-date firmware.  I've also been able to
successfully authorize the Thunderbolt eGPU enclosure, and see the RX 580 in
lspci, see blow:

Here are my system details:

System: Dell XPS 15 2 in 1 (Kaby Lake G)
Kernel: 4.19
Mesa: 18.2.2
Xorg: 1.20.1
Built in GPUs: Intel iGPU, Vega M
eGPU: RX 580

I'm not sure if I'm having problems because my laptop *also* contains a Vega M,
which also uses the amdgpu driver.  Perhaps there's a problem if there are
multiple GPUs using amdgpu?  One thing to point out is that the Vega M has
worked flawlessly since Kernel 4.18.x.

I did run across several other users posting about this same problem when
attempting to run AMD GPUs as eGPUs.  Here's a post where a user is reporting
the same issue:

https://egpu.io/forums/thunderbolt-linux-setup/egpus-under-linux-an-advanced-guide/#post-33304

And here's another post:

https://forum.manjaro.org/t/rx-580-in-a-thunderbolt-egpu-dock/58210

I'm comfortable applying and testing kernel patches, so please feel free to ask
me to test any fixes.  I'm currently running 4.19, but could also patch a
4.18.x kernel.

Thanks!
