Hi,

I don't know if this is related at all, but since installing 12-current 
on rpi3 (latest snapshot), it won't come back up after a shutdown -r 
now, or from the reboot command. I have to *unplug the power*, wait 30s 
[1], then plug it back in for it to come back up [2].

[1] not 10 or 15 or 20s, it *has* to be 30s or over.
[2] snapshot was r336134. in-situ source upgrade to r336215, problem 
persists.
