Using the mini.iso of Ubuntu 16.04 LTS on a Intel NUC NUC5CPYH (most current UEFI update), the installation runs smoothly. But after the restart at the end of the installation, the NUC hangs at
/dev/sda1: clean, 291272/4292608 files, 480345/18174432 blocks
Update: After removing 'quiet' from the boot options, I can see that boot hangs on "Starting Show Plymouth Boot Screen...torage."
Nothing ever happens. What's the problem here?
