So I applied all patches to drm-intel-next-2016-03-30 (tag from drm-intel-nightly). I still do have my specific error (underrun FIFO), which apparently results into black screen flickering:

[ 1.307318] [drm] Finished loading i915/skl_dmc_ver1.bin (v1.26)

Thanks anyways, it was worth a try.

btw: The bogus alignment and training clock error was after I recovered from suspend.
