eGPU failed to initialize

Thu Jan 2 09:08:07 UTC 2020

Hi Qu,

that problem is completely unrelated to amdgpu. See you thunderbold 
bridge fails to assign the necessary I/O resources to the PCI device 
long before amdgpu even loads:

 From your dmesg:

This is a rather unusual problem and I have no idea how you ended up 
with that. But with this setup it is impossible for the driver to access 
the device.

Christian.
