<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>
<p>Adding Christian for this.</p>

<div dir="ltr">Also, to clarify... if I move it into a regular

Tested with Intel iGPU enabled and disabled, made sure i915
loaded without error and can connect display to it.<br>

<div dir="ltr">Hello all,
<div><br>
</div>
<div>I've got a Powercolor Red Devil Vega 56 here that I'm
trying to get working in eGPU mode.<br>
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>
<br>
Set loglevel=8 doesn't get any additional messages.</div>
<div>Here's what it does report (full dmesg attached):</div>
<div><br>
</div>
<div>
<div>[ 429.005909] [drm] amdgpu kernel modesetting
enabled.</div>
<div>[ 429.006080] [drm] initializing kernel
modesetting (VEGA10 0x1002:0x687F 0x148C:0x2388 0xC3).</div>
<div>[ 429.006082] amdgpu 0000:16:00.0: Fatal error
during GPU init</div>
<div>[ 429.006155] amdgpu: probe of 0000:16:00.0 failed
with error -12</div>
<div><br>
Using the following commands to unload & reload
for testing. Since it's as an 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><br>
</div>
<div>sudo rmmod amdgpu</div>
<div>sudo modprobe -v amgpu</div>
<div><br>
</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 dump. uname -a
below:</div>
<div><i>Linux testbox 4.15.15-041515-generic
#201803311331 SMP Sat Mar 31 17:34:21 UTC 2018
x86_64 x86_64 x86_64 GNU/Linux</i><br>
<br>
Any other ideas on how I can debug this further? Feel
I'm so close, don't want to let this go.</div>
Thank you in advance for your time.<br>
