Though, this iteration brings the issue back at least during boot when i915.ko is loaded: My J5005-ITX prints it's boot messages after powering on the system. Then, when i915 first initialises the hardware and switches the FB to 1080p50 (forced via "video=HDMI-A-1:1920x1080@50" on the kernel command line), I get the "No signal" problem. Shortly after, when X and Kodi are started, the picture returns due to some "xset" commands that are run. From within Kodi, playing a 23.976p movie and stopping (thus switching to 1080p50 again), picture remains and there are no more issues. Maybe the connector check causes the initial issue here? For reference, the backported patch is at [1] and kernel debs at [2].
