            Bug ID: 101834
           Summary: WebGL shaders cause system freeze
           Product: Mesa
           Version: 17.1
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: grmat at sub.red
        QA Contact: dri-devel at lists.freedesktop.org

Hardware:
Radeon R9 290X (Hawaii)

Installed components:
Linux 4.11.9
Libdrm 2.4.81
Mesa 17.1.4

Running Arch Linux, using both radeon and amdgpu drm drivers, Chromium and
Firefox the system can freeze when running WebGL shaders. I've experienced this
on shadertoy.com before and now have a reproducible example:

Sound keeps on playing and I can move the cursor but not interact with the
system any more. If I can provide any logs to help, please ask.
