Hello everyone!

I have some troubles with the amdgpu driver.

I'm getting some errors from the kernel when I force to use the discrete GPU.
By the way, I have a hybrid GPU System. (Lenovo Laptop: Intel HD & AMD Radeon
530)  

First of all I cleared the dmesg logs.

Then I executed:

DRI_PRIME=1 glxinfo | grep OpenGL

and then I got this errors:

But when I set the DRI_PRIME value to 0, this errors doesn't appear.

I also tried with DRI_PRIME=1 glxgears.

There I get TONS of errors like this here:
[  422.628301] amdgpu 0000:01:00.0: couldn't schedule ib on ring <sdma0>
[  422.628328] [drm:amdgpu_job_run [amdgpu]] *ERROR* Error scheduling IBs (-22)

I am using the latest version of OpenSUSE tumbleweed.
Kernel: 4.19.12-1-default

amdgpu is installed & kernel-firmware, too.

Thanks!!
