halt is fine btw, it's only reboot that breaks. Do you want extra debug turned on for dmesg?
At Linux 19.0-rc8, power button / halt command also fails. The backlight goes off but the power stays on.
Can you bisect that? Is it the same commit?
It is the same commit i.e. 0a1d565 built from the stable tree consistently fails to power off. 30cdbfa *sometimes* fails to power off - I think I have seen 2 fails in6 reboots (my spreadsheet isn't set up to count results (yet)).
