            Bug ID: 100460
           Summary: AMDGPU system hang with Slic3r Prusa Edition
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: greg@chown.ath.cx

The 3D printing software Slic3r Prusa Edition uses OpenGL to render 3D views of
objects and a preview of the tool path.

The tool path preview causes system hangs for me with AMDGPU and RadeonSI, with
the latest mainline code of all components involved (Linux 4.11rc4, Mesa git,
LLVM svn). It seems to be memory management related. It looks like there may be
a deadlock of some sort.

Here's how to reproduce. I wasn't able to record a working trace.

1. Download Slic3r Prusa Edition 1.33.8 from
https://github.com/prusa3d/Slic3r/releases/tag/version_1.33.8 (AppImage is the
easy choice)
2. Get the model "LASER CAT - Voronoi Style" from
http://www.thingiverse.com/thing:179266/#files (e.g.
Laser_Cat_-_Voronoi_coarse.stl)
3. Start Slic3r, abort setup wizard. Default settings are fine.
4. Press "Add..." and select the .stl file
5. Press "Slice now" in the right panel
6. Select "Preview" in the bottom tab list

This results in a hanging system. The kernel's hang detection is triggered
after a while:

The application possibly might not behave well, but this should never happen
nonetheless.
