SubjectRE: PROBLEM: Intel HDMI output busticated on 4.4 (regression)
Hi Nick, 

Sonika is OOO for this week.
AFAIK about this issue, looks like the live status is not getting set for your system, on HPD.

As per the Bspec, we must check live status before trying to read EDID.
Is it possible for you to check with an HDMI analyzer and probe live status register ?

HDMI is still broken on my system in 4.5-rc3.
