            Bug ID: 100424
           Summary: X hang (in kernel) after some event in Serious Sam
                    Fusion using radv. 4.9/and-staging-4.9
           Product: DRI
           Version: DRI git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: bugspam@moreofthesa.me.uk

To reproduce, play Serious Sam Fusion (Vulkan rendering). X should freeze after
a few minutes; at the start of SS:TFE, venturing out into the desert or killing
an gnaar should be enough to trigger it.

It looks like a fence + buffer object 'interaction'.

This appears to affect all Linux 4.9.x and amd-staging-4.9; other kernels are
as yet untested.

Mesa 17.0.2 or git, libdrm 2.4.75, llvm 4.0~svn294803. Hardware is RX 470.
