Hi Alex,

Thanks for the reply.  I wanted to clarify an important point: When I disabled
PM completely and ACPI completely, I did not see any PCI resource issues AND
the eGPU initialized successfully.

However, after testing a little more I was able to keep the PM enabled and only
disabled ACPI.  In this situation I encountered a scenario where the PCI
resource issues were present in the log, BUT the eGPU still initialized.  I
mentioned that briefly in one of my previous comments but didn't really
elaborate.

So under certain situations the eGPU did initialize despite seeing PCI BAR
resource issues.

I've been working with another user that has the exact same system (XPS 9575)
and an RX 580 and is having the same issues.  He was actually able to get the
eGPU initialized by passing in PCI=noacpi rather than completely disabling ACPI
as a whole.  I'll double check with him to see if he can post his dmesg log -
because I'm not sure if the PCI resource issues are present under those
circumstances.

Reference:
https://forum.manjaro.org/t/rx-580-in-a-thunderbolt-egpu-dock/58210/13

At this point I've had to return my RX 580 - great card but after about a month
of troubleshooting I was running out of time in the return window - so I'm
unable to do any more testing with that specific card at this time.  Kind of a
bummer... I'll probably pick up a Vega early next year and try again.

Rob
