            Bug ID: 106527
           Summary: OpenCL corrupted memory on AMD R9 280X
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu-pro
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: riccardodemaria@gmail.com

I am trying to use the AMD R9 280X (Tahiti) with the latest Ubuntu 18.04 and
AMDGPU-PRO driver.

OpenCL appears to work with 

export GPU_FORCE_64BIT_PTR=1

see https://bugs.freedesktop.org/show_bug.cgi?id=102491

however the memory appears corrupted on the device resulting in random data
populating partially or entirely the buffers.

A simple OpenCL program is sufficient to show the problem:

in my case.
