RX590 - amdgpu failed on new Kernels

Question asked by coosee on Apr 2, 2019

hello,

 

i use Qubes OS System and Kernel 4.14.103 works fine, but when i try to use any newer Kernel, the login to Desktop failed.

 

there are also some artifacts at lightdm login, please look at the atttachment.

 

i also tried a manually compiled kernel, but the result is almost the same.

 

in Xorg.0.log there's the Error - this happens only with newer Kernels:

 

[    62.958] (EE) glamor0: GL error: GL_OUT_OF_MEMORY in glTexSubImage
[    62.958] (WW) glamor: Failed to allocate 22x22 FBO due to GL_OUT_OF_MEMORY.
[    62.958] (WW) glamor: Expect reduced performance.

 

i also tried the current Version of amdgpu Driver- non Pro!

 

the only difference to the 4.14 Kernel is the Module >> gpu-sched >> which is only loaded with newer Kernels, e.g 5.0.2.

 

Is this a Xen Problem or a Driver Problem in context with Xen+newer Kernels?

 

The Card on FunToo Linux works perfect, no Problems at all.

 

thx
