No, I haven't reported the EDID issues yet as I haven't yet collected enough
info to make a decent bug report.

There's definitely some sort of bug. Sometimes no EDID, sometimes EDID but the
connector isn't enabled. I have a Raspberry Pi 2 connected to the same hardware
with the same cable and it works 100% of the time so I don't think it's the
other side.

I'll give drm-intel-nightly a try and report back results.
