Hey guys!

I've just updated my Intel and AMD drivers because BOINC always had hickup on the calculation via AMD GPU (PC renewed, also replace GPU meanwhile) and now BOINC says, that there is no OpenCL supported GPU, which is clearly nonsense:

25.04.2016 18:34:25 | | Starting BOINC client version 7.6.22 for windows_x86_64

25.04.2016 18:34:35 | SETI@home | Scheduler request completed: got 0 new tasks



It says OpenCL devices found and after that, that there is no OpenCL supported device. That doesn't make any sense (also not that the IntelGPU is being offered by AMD and Intel OpenCL/APP driver/connector).

Any ideas how to fix that?

It looks like the opencl 1.2 on the amd gpu is getting over written by the opencl 2.0 of the intel gpu. The hd5000 series can not run opencl 2.0, I would suggust backing the intel gpu driver to a version that contains opencl 1.2
