Graphical issues with Fedora 27

Hi,

I recently upgraded my old system hardware using Fedora 19 and went to Fedora 27. My hardware is an asus prime b350m-e motherboard with an amd 2400g processor. My kernel is 4.16.7-200.fc27.x8664 x8664. I initially had may issues until I installed the xorg-x11-drv-ampgu (AMD GPU video driver, verison 18.0.1). It is much much better but I still have a couple more issues.

  1. Every so often, the system hangs. I do not have any mouse/keyboard response and hence, I can not get a console window using ctrl-atl F2 either. After rebooting, I examine journalctl. I often see this before hanging (but not always)

May 15 06:49:32 localhost.localdomain kernel: [drm:amdgpujobtimedout [amdgpu]] ERROR ring sdma0 timeout, last signaled seq=279832, last emitted seq=279835 May 15 06:49:32 localhost.localdomain kernel: [drm] IP block:psp is hung! May 15 06:49:32 localhost.localdomain kernel: [drm] GPU recovery disabled.

Any thoughts for this? Is there some better diagnostic approach to use to find the source(s) of the problem?

  1. I have noticed that the linux command "import" is not working properly. I get the same behaviour on another Fedora 27 system (completely different motherboard and processor). Attached is an image of the behaviour. I get ghost lines were the rectangular selection window has paused before the final selection is made. I do not know where the issue lies, with the import utility form imagemagick or the os. Any thoughts?

Al

ERROR ring sdma0 timeout, last signaled seq=279832 It looks like there is an upstream (Freedisktop.org) bug about this: https://bugs.freedesktop.org/show_bug... which suggest the bug might be related to mp4 video decoding.

An other one: https://bugs.freedesktop.org/show_bug...

This one for Fedora 29: https://bugs.freedesktop.org/show_bug...

My search url: https://bugs.freedesktop.org/buglist....

Do you have a calltrace after this message? (with just about timestamp at the begin of the line)?

I guess it will not help you much, but I see there exist a debugger for amd gpu: https://cgit.freedesktop.org/amd/umr/... which is described a little more at: https://www.phoronix.com/scan.php?pag...

What is SDMA? https://www.phoronix.com/scan.php?pag...

https://01.org/linuxgraphics/document... might help

https://apps.fedoraproject.org/packag... I guess you could try to remove libva package (disabling hardware video decoding) to see if it help... In fact the following packages seems related:

vdr-vaapidevice.i686 : A VA-API output device plugin for VDR
vdr-vaapidevice.x86_64 : A VA-API output device plugin for VDR
gstreamer1-vaapi.i686 : GStreamer plugins to use VA API video acceleration
gstreamer1-vaapi.x86_64 : GStreamer plugins to use VA API video acceleration
gstreamer1-vaapi-devel-docs.noarch : Developer documentation for GStreamer VA API video acceleration
                                   : plugins
===================================== Résumé correspond : vaapi ======================================
libva-utils.x86_64 : Tools for VAAPI (including vainfo)
libvdpau-va-gl.i686 : VDPAU driver with OpenGL/VAAPI back-end
libvdpau-va-gl.x86_64 : VDPAU driver with OpenGL/VAAPI back-end

You might also consider booting linux asking to use radeon driver rather than amdgpu with:

amdgpu.si_support=0 radeon.si_support=1
