<br>
nice to know that you got it working.<br>
<br>
And it is an interesting rational that disabling thunderbolt boot
support in the BIOS fixes thinks. Going to keep that in mind when
other users run into the same issue.<br>
<br>
Thanks,<br>
Christian.<br>

</div>
<div>Thanks for the response. That got me in the right
direction.</div>
<div>After trial and error I found the cause - Thunderbolt Boot
Support option must be disabled in BIOS.</div>
<div>If I disable it I can boot to Ubuntu and looks like amdgpu
inits okay. If I enable with no other changes, init fails.</div>
<div><br>
</div>
<div>The last issue was one of my own - forgetting to use
DRI_PRIME and xrandr correctly.</div>
<div>Happy to say the Red Devil is working now in eGPU mode! <br>
It's about a 20% perf loss over PCI-E slot and right in line
with our previous tests.<br>
<br>
As always thank you for your continued time and support.<br>
We'll be happy to give a shout out to you guys for the help at
article/video time.</div>

Daniel,<br>
<br>
your problem is that the system BIOS is buggy and
doesn't assign resources to the card:<br>

Region 2: Memory at <ignored> (64-bit,

Region 5: Memory at <ignored> (32-bit,

<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>

I'll take another look at the BIOS settings to see

<p>Just from a quick look it seems to fail in
