I have a pi3B which boots fine from power on with a Kingston A400 120Gb SSD and latest raspbian image fully updated. It works like a charm until I go to reboot it, then it always just seems to hang and I need to manually cycle the power to get it back on. At this point it boots fine.
Can anyone suggest a solution to allow it to reboot properly without the need to cycle the power?
Also, having copied a 16Gb image to the ssd, I can't expand it with the raspi-config tool as it is not a sd card. So how can I maximise the space available by expanding to the full availalble space as I did with SD cards?
