--- Comment #19 from Daniel Vetter <daniel at ffwll.ch> ---
Ok, we need to split this bug up.

- has_infoframes mismatch is tracked in bug #93119 - if the test fails only due
to that then it's a dupe of that

- let's restrict this one here to hsw crc failures due to fifo underruns. This
bug only happens (at least for me) when both a VGA plus either hdmi or dp
output are present. VGA alone or any other combo without vga works. I have a
patch for this bug, hence will take it over. Because bdw doesn't have vga this
bug can't happen there.

If there are any other bugs then we need to track them in other bugzillas (if
an applicable is filed already) or file a new one.
