Title:
Black Screen on 18.
Since commit ca876c7483b6 ("gpiolib-acpi: make sure we trigger edge
events at least once on boot") in the Linux mainline v4.18 kernel (and
also in stable v4.14.68 as commit fbb37b72489d) the Linux kernel now
calls _AEI edge handlers at boot.
Unfortunately the MINIX Neo Z83-4 mini PC has a DSDT bug
Attached is the patch (or commit
b607990c76ceda0a7a7ceacabab174cdc8b9beee).

A mainline patch is available now in v4.17-rc4.
It is probably best to back port commit
b607990c76ceda0a7a7ceacabab174cdc8b9beee for Ubuntu 4.15 and Ubuntu 4.16
(if released) as the mainline 'Cc: stable' tag is stalled.
The patch/commit fixes the bug as documented above:
