Beignet: Warning - overriding self-test failure

Beignet is blacklisted in darktable. You could try to remove it from the list and recompile darktable and see if it works: https://github.com/darktable-org/darktable/blob/master/src/common/opencl_drivers_blacklist.h Line 27. Darktable devs have disabled Beignet because they see not much gain in using intel cards with opencl. You can read more about it here: https://www.darktable.org/2012/03/darktable-and-opencl/
