Don't know how much we can help with that. Seems very specific to your device. -5 means CL_OUT_OF_RESOURCES and the drm_intel_gem_bo_context_exec() failed: Invalid argument seems to be related to your drivers.

Googling around seems there are some recent bug reports about integrated Graphics on Haswell processors and this particular message.

Also this issue should be in cpp-ethereum, not here. This repo is only for the ethash C library code.

[chfast]

The problem is with the CL kernel. Shouldn't the issue belong here then?
Besides that, I agree with the rest.

[LefterisJP]

no, anything OpenCL related goes in cpp-ethereum. If you look closely you will notice there is no longer any GPU/OpenCL related code in this repo
