AMD A8-7600 Kaveri (SMP 2 cores)
APU R7 Graphics (Spectre) (GPU slot)
GPU: Radeon 6850 (Barts) (GPU slot)
Core 17 runs fine on both GPUs. Core 21 runs fine on the graphics portion of the APU. Core 21 on the 6850 causes a display driver reset several times and a complete lock-up once.
Does Core 21 require OpenCL 2.0 support or does it have an OpenCL 1.2 code path as well?
In the log below you can see that Spectre supports OpenCL 2.0 but the CPU and 6850 do not. Is it possible the detection code finds that one GPU supports 2.0 and then incorrectly attempts to use that on the 6850, which only supports 1.2?
