Description RobusGrobus95 2018-10-06 20:07:38 UTC
GPU hang appears when trying to render scene to FBO (framebuffer object) with attached texture with resident handle, but if all the handles of attached texture are not reesident (or if there is no handles), hang disappears. For example this pseudocode causes GPU hang:
  GLuint renderbufId;
  glCreateRenderbuffers(1, &renderbufId);
  glNamedRenderbufferStorage(renderbufId, GL_DEPTH_COMPONENT, width(), height());

  GLuint texId;
  glCreateTextures(GL_TEXTURE_2D, 1, &texId);
  glTextureStorage2D(texId, 1, GL_RGBA8, width(), height());

  GLuint64 handle = glGetTextureHandleARB(texId);
  glMakeTextureHandleResidentARB(handle);

  glBindFramebuffer(GL_FRAMEBUFFER, fboID);
  glFramebufferTexture(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, texId, 0);
  glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, rboId);
  //render some triangles
  glBindFramebuffer(GL_FRAMEBUFFER, 0);
  //render main scene
  glSwapBuffers();

And this not:
  GLuint renderbufId;
  glCreateRenderbuffers(1, &renderbufId);
  glNamedRenderbufferStorage(renderbufId, GL_DEPTH_COMPONENT, width(), height());

  GLuint texId;
  glCreateTextures(GL_TEXTURE_2D, 1, &texId);
  glTextureStorage2D(texId, 1, GL_RGBA8, width(), height());

  GLuint64 handle = glGetTextureHandleARB(texId);
  std::cout << handle << std::endl; //prevent optimizing out

  glBindFramebuffer(GL_FRAMEBUFFER, fboID);
  glFramebufferTexture(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, texId, 0);
  glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, rboId);
  //render some triangles
  glBindFramebuffer(GL_FRAMEBUFFER, 0);
  //render main scene
  glSwapBuffers();

I can try to write full cpp sample for exposing the hang, if it's needed. There is already open source graphic engine (my "pet" project) affected by the hang, but code is quite complex (https://gitlab.com/KawaiiGraphics/Kawaii3D https://gitlab.com/KawaiiGraphics/Misaka3D ; 
workaround added in commit b53d98dacff2b0392c2143c8901289e93ddd8623, so only previous versions are affected).

My hardware:
APU: AMD Ryzen 5 2400G (with integrated GPU Radeon Vega 11 Graphics)
System board: MSI AM4 X470 Gaming Pro
RAM: Goodram Iridium 16Gb (8+8 Gb dual-channel 2800MHz)

We have same issue. Could you link fault info from kernel messages ?
