[Bug 108521] RX 580 as eGPU amdgpu: gpu post error!

https://bugs.freedesktop.org/show_bug.cgi?id=108521

--- Comment #11 from Robert Strube rstrube@gmail.com --- I disabled a bunch of devices in the BIOS (sound, SD card reader, etc.) and I confirmed that they are no longer showing up in lspci, but I'm still getting the same error.

I also found one suggestion to pass in a kernel parameter of hpbussize=4 to increase the bus size made available for hot-pluggable devices, this also didn't help.

Thanks for all your assistance BTW!

Any other suggestions? I'm starting run out of options here.

Thanks!
