Bug ID: 101584
Summary: clover: ethminer -G --benchmark: ring buffer overflow,
GPU faults
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi

dmesg
Tested with my RX 480 on mesa git and Linux 4.11 and 4.12-rc.
To reproduce, get https://github.com/ethereum-mining/ethminer
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.
