dmesg
Tested with my RX 480 on mesa git and Linux 4.11 and 4.12-rc.
To reproduce, get <a href="https://github.com/ethereum-mining/ethminer">https://github.com/ethereum-mining/ethminer</a>
in libethash-cl/ethash_cl_miner_kernel.cl add
#pragma OPENCL EXTENSION cl_clang_storage_class_specifiers : enable
then cmake . and make and in ethminer/ run ./ethminer -G --benchmark
it outputs some progress and at 97% something goes wrong and I get GPU faults
and/or GPU hangs.
Interestingly with the closed source OpenCL runtime from amdgpu-pro it fails at
97% too.</pre>
