Frame buffer ig-platform-data in AppleIntelBDWGraphicsFramebuffer is 136 bytes.
You're showing only 112 bytes of the data.

I gave up on 10.12.4 and reinstalled 10.12.3 where with the exact same config everything works fine. I wonder if all Broadwell/HD5500 users experience this problem or if it's due to certain specs (e.g. a FHD screen or not being able to set DVMT-prealloc via BIOS).

Maybe this issue is worth a note/warning in the "[README] Common (some unsolved) Problems in 10.12 Sierra" thread.

You should compare the ig-platform-id data from each version.

CPU:I5 52000U HD5500

macOS 10.12.3 is normal
(ig-platform-id=16160002 Wake up black screen(Only backlight))
(ig-platform-id=16260006 Wake is normal)

macOS 10.12.4 wake up black screen(Only backlight)
(ig-platform-id=16160002 and 16260006 Wake up black screen(Only backlight))

How to fix it?
this is the problem of 4 update, where 1626006 and some others were broken. For me 16260002 or 16260004 works good, but additional fixed is required.
