            Bug ID: 111123
           Summary: Display issues AMD RAVEN Ryzen 5 3400G APU
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: freedesktop at redsandro.e4ward.com

I'm having issues using hardware accelerated graphics on my AMD Ryzen 5 3400G
with A300M-STX mainboard and A300 chipset by ASRock.

That's the AMD Ryzen 5 3400G with Radeon Vega Graphics (family: 0x17, model:
0x18, stepping: 0x1)

When attaching an UHD (4k) monitor over the DisplayPort, everything works as
expected as long as I am running an older kernel that doesn't support the APU
video hardware. E.g. 4.15 or 4.18.

When I use 5.0, 5.1 or 5.2 kernel, the _same display connection that worked
fine before_ doesn't work anymore. The image keeps disappearing, shaking,
distorting and creating green pixel noise, as if the cable is bad quality.

When starting those same kernels with `nomodeset` from GRUB, the image is
stable again, but the hardware acceleration is disabled.

HDMI works fine on a HD display (1920x1080) but also no picture on UHD.

HWE Kernel does have hardware rendering, but shows the

[    1.296083] kfd kfd: DID 15d8 is missing in supported_devices
[    1.296084] kfd kfd: kgd2kfd_probe failed

So I used Ukuu to install 5.2.0-RC7.
