Hello,
while trying to use the NUC DN2820FYK [1], screen goes black as soon
i915 is loaded. The NUC is connected by HDMI to a 1920x1080 display.
Works normally while on the BIOS (upgraded to the latest one just in
case today) and while on grub. Here's what I tried:
- nomodeset: partially works, text mode keeps flickering and X has lines
out of place
- enable_rc6={0,2,3}, no result
- drm_kms_helper.edid_firmware=edid/1920x1080.bin (no
/usr/lib/firmware/edid in this box but from what I found this
specific one is supposed to be built in)
Tested with kernel: 0b7962a6c4a37ef3cbb25d976af7b9ec4ce8ad01 (top of
Linus' today)
My best guess on messages [2]:

On /sys/class/drm/*/status, in both cases are 'disconnected'.
I also captured the lspci [3].
Anything I could try or perhaps any other information I can gather?
Thanks
