<pre>Hello,
I think I have the same problem as all the others here.
My setup - working fine under Windows - is:
* HP Spectre x360 - chxx model with the i7-8705 CPU (so also with an vega M
dGPU
* Razer Core X with AMD Vega56
A normal boot with Kernel 5.3.7-2 gives me this in dmesg:
[ 11.672442] [drm:atom_op_jump [amdgpu]] *ERROR* atombios stuck in loop for
more than 5secs aborting
[ 11.672469] [drm:amdgpu_atom_execute_table_locked [amdgpu]] *ERROR* atombios
stuck executing CF4E (len 1030, WS 8, PS 0) @ 0xD2C5
[ 11.672492] [drm:amdgpu_atom_execute_table_locked [amdgpu]] *ERROR* atombios
stuck executing C410 (len 114, WS 0, PS 8) @ 0xC41C
[ 11.672495] amdgpu 0000:09:00.0: gpu post error!
[ 11.672496] amdgpu 0000:09:00.0: Fatal error during GPU init
[ 11.672497] [drm] amdgpu: finishing device.
but I also found some errors like this: Do they have to do something with our
GPU?
[ 2.732913] ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D128] at bit
offset/length 128/1024 exceeds size of target Buffer (160 bits)
(20190703/dsopcode-198)
[ 2.732919] ACPI Error: Aborting method \HWMC due to previous error

[ 2.732927] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error
(AE_AML_BUFFER_LIMIT) (20190703/psparse-529)
I also have some of those BAR-errors, but I never have them with the PCI Adress
of the eGPU only with other adresses:

@Robert Strude: You wanted to buy a Vega and make some researches with it. As
you can see there is still something wrong here. Perhaps you are interested and
want to help me finding more information.</pre>
