<div class="m_-6687502937288805473moz-cite-prefix">Hi Daniel,<br>
<br>
your problem is that the system BIOS is buggy and doesn't assign
resources to the card:<br>
<blockquote type="cite"> Region 0: Memory at <ignored>
(64-bit, prefetchable)<br>
Region 2: Memory at <ignored> (64-bit, prefetchable)<br>
Region 4: I/O ports at 9000 [size=256]<br>
Region 5: Memory at <ignored> (32-bit,
non-prefetchable)<br>
Expansion ROM at <ignored> [disabled]</blockquote>
<br>
The kernel actually tries to assign resources to the bridges, but
fails as well because the BIOS didn't reserved any during startup.<br>

There isn't much you can do except for trying to update the BIOS
and if that doesn't help replace your motherboard.<br>

Thank you for the responses.</div>
<div>Here's the requested dmesg/lspci. Also pulled journalctl
just in case but didn't see anything that stands out.</div>
<div><br>
I'll take another look at the BIOS settings to see if anything
else may explain the memory error.</div>
<div>I've got 16GB in the system at the moment, can bump up to
32 - also added a larger swap just in case that was the issue.
(No change.)<br>

As always thank you for your continued time and support.</div>

<p>Just from a quick look it seems to fail in
amdgpu_device_init->ioremap with ENOMEM, that would
explain why you don't see any more prints - this
failure is very early in the device init process.</p>
<p>No idea why ioremap would fail in this case and not
even sure which implementation of ioremap to look into
for your case.</p>

I think on the BIOS/hardware side it's now
all fleshed out.</div>
<div>Now I'm at a point where amdgpu tries to
init and reaches a fatal error.<br>

Set loglevel=8 doesn't get any additional

Using the following commands to unload

eGPU I'm using the i7-7700K iGPU (i915
module) as the primary and these commands
work in terminal without requiring a
reboot.</div>

<div>sudo rmmod amdgpu</div>
<div>sudo modprobe -v amgpu</div>

<div>Pulled the UMR and tried to make, fails
on Cmake. I'll attach log in a text.<br>
Also will attach a full dmesg and lspci
