dmesg log booting system *without* eGPU

So I decided to do a sanity check and completely remove the eGPU from the
equation.  I am still getting the BAR errors in dmesg, so perhaps this isn't
the problem after all?!

The one thing I noticed is that the BAR errors are for the pci module and not
the pcieport module.  One other thing worth mentioning is that I tried with a
different GPU (for the eGPU) yesterday.  I had a GTX 1060 available, and this
*did* work correctly.  I haven't double checked if the BAR errors are present
with the other GPU.

Perhaps it is a bug with amdgpu after all?
