AMDGPU module refuses to load with Radeon RX 570 card


I just installed 14.2 here, and started X and my second monitor wasn't working. Okay, weird I thought. SO I updated and rebooted and it still wouldn't display anything after running startx. As it turns out, the AMDGPU kernel module isn't even loaded and refuses too when trying to start it with insmod. Glxinfo also lists my vendor as VMware.

The amdgpu package is installed of course, I even tried reinstalling it to no avail.

dmesg log after attempting to load amdgpu module with insmod

http://dpaste.com/08P1SBA

output of glxinfo

Code:
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
    Vendor: VMware, Inc. (0xffffffff)
OpenGL vendor string: VMware, Inc.

Have you got an amdgpu kernel module from a different kernel version? Try
Code:
uname -r
and
Code:
modinfo amdgpu | grep vermagic

They both say 4.4.172, so unfortunately no.

What device do you have? It's very possible that it requires a newer kernel than what comes in 14.2.

Kernel 4.4 is quite old, you might try installing the kernel-{firmware,source,huge,generic,modules} packages from -current.

Post your full dmesg log? It probably complains about something before that, like missing firmware.

The card show up properly under lspci? lspci -v should tell you what module it *is* using, like:

Code:
0b:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Vega 10 XL/XT [Radeon RX Vega 56/64] (rev c1) (prog-if 00 [VGA controller])
        Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Vega [Radeon RX Vega]
        ...
        Kernel driver in use: amdgpu
        Kernel modules: amdgpu

I did just realize that you had the device in the title... my bad.

Before you upgrade the whole kernel, you could try just installing the updated kernel-firmware package, as maybe there was an updated firmware for your device.

I know this is going to be a let down for anyone else having this same issue, but I just went ahead and installed -current and it's working fine now. so it probably was because of the kernel being too old in 14.2.
