    Description

    Created attachment 102434
    kernel messages

    Tried running Unreal Engine 4 demos from https://wiki.unrealengine.com/Linux_Demos
    'Mobile Temple Demo' started, worked bad (image was too dark, possible to see almost nothing), but did not crash anything.
    Next tried 'Effects Cave Demo': in a few seconds after first start of demo X server became not responding (not even possible to switch with ctrl+alt+f1), it was flickering between grey fill and normal desktop (seems kernel tried to restart GPU), then system became fully unresponsive: ssh did not work, power button did not send system to suspend. Attached kernel messages saved by syslog.

    I never had GPU related stability problems with 3.12.x-3.14.x kernels before: several opengl 3d games worked fine, opengl based mpv video output worked fine, glxgears and stellarium worked fine too.

    Did unreal engine try to use some non implemented or unstable features? Why kernel allowed to crash itself instead of killing userspace app?

    Hardware: Radeon HD 6770
    Software: Gentoo hardened amd64 stable, kernel-3.14.10, libdrm-2.4.54, mesa-10.2.2, llvm-3.3, xf86-video-ati-7.3.0, xorg-server-1.15.0

        I tried the Effects Cave Demo on a Radeon HD 6950: After it loaded the sound played but the screen was going into standby and the system wasn't even reacting to MagSysRq keys. Would love to give logs but they where wiped with the system reset.

        Now I tried Mobile Temple Demo, too, which played no sound and showed vertical blue lines (garbage I guess) only till the watchdog kicked in.

        I can also reproduce this with the effects demo on this card:
        [AMD/ATI] Redwood XT [Radeon HD 5670/5690/5730]

        I was able to ssh into the machine and kill the application, which restored the display on the X server.

        The following output was seen repeating in the terminal output of the application:

        EE r600_shader.c:157 r600_pipe_shader_create - translation from TGSI failed !
        EE r600_state_common.c:751 r600_shader_select - Failed to build shader variant (type=1) -1

        I have no problems running any demo from that site.

        However - there is some severe and very annoying stuttering. Which I can also replicate on games using that engine...
        Can someone else confirm?

        Yes, it's because of shader recompiles. This is being addressed and will hopefully be fixed before too long. It's not related to this bug report though.

        Thanks for the info. By adressed you mean in the engine or in the driver?
        Also is there a bug report about this / can I track this somewhere?


        @reporter:
        Please check again, this bug can probably be closed...

        This issue hasn't had any activity since 2019-11-19. The AMD driver stack changes rapidly and contains lots of shared code across products so it's possible that it has already been fixed. Please upgrade to a current stable kernel and userspace stack and try again. If you still experience this issue with the latest driver stack, please capture relevant logging and open a new issue referring back to this one.
