In that case, it is probably better to open a new bug report (and refer to this
bug for context) for other issues.

The dGPU and TB devices appear behind different bridges (lspci -tv):
-[0000:00]-+-00.0  Intel Corporation Xeon E3-1200 v6/7th Gen Core Processor
Host Bridge/DRAM Registers
           ...
           +-1c.0-[01]----00.0  Advanced Micro Devices, Inc. [AMD/ATI] Lexa XT
[Radeon PRO WX 3100]
           ...
           +-1c.4-[03-3b]----00.0-[04-3b]--+-00.0-[05]----00.0  Intel
Corporation JHL6340 Thunderbolt 3 NHI (C step) [Alpine Ridge 2C 2016]

Maybe related (or maybe not), that's why I was asking for some detail (thanks
for providing these!). But please do open a new bug since the original issue
appears to be solved.
