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: https://github.com/rdemaria/opencl_simpletest in my case.
